Ok, it's not really a site that's trying to get people robbed. It is, however, an example of the down side of Twitter. From the site's Why page...
Hey, do you have a Twitter account? Have you ever noticed those messages in which people tell you where they are? Pretty annoying, eh. Well, they're actually also potentially pretty dangerous.When you tell people where you are you are also telling them where you aren't. Like, at home. People forget that this is all still very new. Most people under the age of 20 have never known a world without cellphones or the 'Net. But it has only been 15 or 20 years since these technological wonders became mainstream. Society hasn't caught up yet. At least the non-techie part of it. The techies at least have some idea of the consequences.
Us tech geeks need to do more to educate the normal people about the other side of the coin. This site is one such effort.
