People tell us they’re sometimes worried about sharing information
Well, yes! That's the main reason why many people doesn't like Facebook. There are so many users that don't even try an app just for the fact the they can only register with a Facebook account.
And why developers are using this type of login more and more? Because **information**. In any type of business having user information is very important, with this new *anonymous* login Facebook is killing one of the more important reason why developers use their system.
But well... now they are *The Social Network* so they can do whatever they want. I don't want to say that this new feature isn't good but when I saw it in the f8 keynote I immediately thought that it was a little hypocrite.
