Dans World

Boy Van Amstel created pleaserobme.com to make a point.

A website called PleaseRobMe claims to reveal the location of empty homes based on what people post online.

The Dutch developers told BBC News the site was designed to prove a point about the dangers of sharing precise location information on the internet.

The site scrutinises players of online game Foursquare, which is based on a person's location in the real world.

PleaseRobMe extracts information from players who have chosen to post their whereabouts automatically onto Twitter.

"It started with me and a friend looking at our Twitter feeds and seeing more and more Foursquare posts," said Boy Van Amstel, one of PleaseRobMe's developers.

"People were checking in at their house, or their girlfriend's or friend's house, and sharing the address - I don't think they were aware of how much they were sharing."

Mr Van Amstel, Frank Groeneveld and Barry Borsboom realised that not only were people sharing detailed location information about themselves and their friends, they were also by default broadcasting when they were away from their own home.

Simple search

The website took just four hours to create.

"It's basically a Twitter search - nothing new," said Mr Van Amstel. "Anyone who can do HTML and javascript can do this. You could almost laugh at how easy it is."

He said that the site would remain live but stressed it was not created to encourage crime.

"The website is not a tool for burglary," he said. "The point we're getting at is that not long ago it was questionable to share your full name on the internet. We've gone past that point by 1000 miles."

Mr Van Amstel added that in practice it would be "very difficult" to use the information on the website to carry out a burglary.

Charity Crimestoppers advises people to think carefully about the information they choose to share on the internet.

"We urge users of Twitter, Facebook or other social networks to stop and think before posting personal details online that could leave them vulnerable to crimes including burglary and identity theft," said a spokesperson.

"Details posted online are available for the world to see; you wouldn't hang a sign on your door saying you're out, so why would you post it online?"

simple idea, isnt always the same though, and he is proving a point sometimes we do give out to much information to our social networks, i for one know i do sometimes. it does stop and make you think about the things you are posting to the world..

A new Buzz start-up experience based on your feedback

We've heard your feedback loud and clear, and since we launched Google Buzz four days ago, we've been working around the clock to address the concerns you've raised. Today, we wanted to let you know about a number of changes we'll be making over the next few days based on all the feedback we've received.

First, auto-following. With Google Buzz, we wanted to make the getting started experience as quick and easy as possible, so that you wouldn't have to manually peck out your social network from scratch. However, many people just wanted to check out Buzz and see if it would be useful to them, and were not happy that they were already set up to follow people. This created a great deal of concern and led people to think that Buzz had automatically displayed the people they were following to the world before they created a profile.

On Thursday, after hearing that people thought the checkbox for choosing not to display this information publicly was too hard to find, we made this option more prominent. But that was clearly not enough. So starting this week, instead of an auto-follow model in which Buzz automatically sets you up to follow the people you email and chat with most, we're moving to an auto-suggest model. You won't be set up to follow anyone until you have reviewed the suggestions and clicked "Follow selected people and start using Buzz."

For the tens of millions of you who have already started using Buzz, over the next couple weeks we'll be showing you a similar version of this new start-up experience to give you a second chance to review and confirm the people you're following. If you want to review this list now, just go to the Buzz tab, click "Following XX people" and unfollow anyone you wish. If you don't want to share the lists of people who are following you and people you are following publicly on your profile, you can opt out at any time from the edit profile page.

Second, Buzz will no longer connect your public Picasa Web Albums and Google Reader shared items automatically. Just to be clear: Buzz only automatically connected content that was already public, so if you had previously shared photos in an "Unlisted" album or set your Google Reader shared items as "Protected," no one except the people you'd explicitly allowed to see your stuff has been able to see it. But due to your feedback Buzz will no longer connect these sites automatically.

Third, we're adding a Buzz tab to Gmail Settings. From there, you'll be able to hide Buzz from Gmail or disable it completely. In addition, there will be a link to these settings from the initial start-up page so you can easily decide from the get go that you don't want to use Buzz at all.

It's been an exciting and challenging week for the Buzz team. We've been getting feedback via the Gmail help forums and emails from friends and family, and we've also been able to do something new: read the buzz about Buzz itself. We quickly realized that we didn't get everything quite right. We're very sorry for the concern we've caused and have been working hard ever since to improve things based on your feedback. We'll continue to do so.

well once again and this time really quickly the guys at Google have listened and have made the changes requested to buzz, i really like the speed and the way that they have made the changes, simple and now really easy for people to opt out of following people on their lists as well as not showing their following lists to the public.

Once again youve done a good job guys at Google, lets hope this will stop the people complaining and start using the service like it should be used, I for one will still be using it as ive really enjoyed the experience so far, and using buzz on the mobile through Google Maps is superb, being able to see people buzzing in your local area allowing you to communicate with people around you really makes this a useful tool.

Millions of Buzz users, and improvements based on your feedback

It's been just two days since we first launched Google Buzz. Since then, tens of millions of people have checked Buzz out, creating over 9 million posts and comments. Plus, we're seeing over 200 posts per minute from mobile phones around the world.

We've had plenty of feature requests, and some direct feedback. In particular there's been concern from some people who thought their contacts were being made public without their knowledge (in particular the lists of people they follow, and the people following them). In addition, others felt they had too little control over who could follow them and were upset that they lacked the ability to block people who didn't yet have public profiles from following them.

Like Gmail's chat service, Buzz helps you create a social network by automatically setting you up to follow the people you email and chat with most. You can change, delete or add any contacts you want to follow.

So here is some more information about how Buzz works, and some immediate improvements we are making today based on your feedback.

The first time you create a post or comment in Buzz, we ask you to create a limited public profile (at a minimum it's just your first and last names). We do this so we'll know what name to display next to your posts — and so the people you follow know who you are. As you do this, we notify you that the lists of people you follow and the people following you will be displayed on your public profile. You can view, edit, and even hide these lists. The lists of your followers/people you follow are not made public on your profile until after you go through this profile creation step.

That said, we heard from people that the checkbox for choosing not to display this information was too hard to find, and based on this feedback, we've changed the notice to make it very clear. We will roll these changes out to all Gmail users later today.

1. More visible option to not show followers/people you follow on your public profile
If you don't want to share the lists of people who are following you and people you are following publicly on your profile, you can always opt out during the profile set-up when you first use Buzz or at any time from the edit profile page. We are making this option more prominent in the set up process, to ensure everyone who wanted to hide these lists can do so easily.

2. Ability to block anyone who starts following you
We are making it easier to block anyone, by adding "Block" links to the list of people following you. Previously, you were only able to block people from following you after they had created a public profile. Now, you can block anyone, regardless of whether or not they've already created profiles for themselves.

3. More clarity on which of your followers/people you follow can appear on your public profile
Initially, we showed you a list of all the people who would be following you once they created a public profile. However, only those contacts who had already created a public profile would show up on your public follower list. We're making this clearer by explicitly distinguishing which of your followers have public profiles and will show in your public list of followers. With this change you'll be able to see who is on the public list of followers that everyone else sees.

people complained about the settings not being easy to find, also about the fact that they thought their lists where being made public to everyone.

they have also added the ability to block users who are following you, all i have to say is Google have listened and done what the people have asked, and they did it pretty quickly good job guys.

Id really like to see Buzz grow now, I myself am using it daily and am really enjoying it, for me the best usage so far has been through Google maps and the Buzz layer, being able to see on the map where people are buzzing from and being able to interact like this has been great.
