In other social software, the software does what the user tells it to do and usually creates a profile about what a person says about themself. Xfire takes this to the next level. It creates a profile about a user actually does, and allows others to see it. Imagine if you will, running a piece of software that watched what you did online. It could tell where you spent your time online and what you were connected to currently. If you were in an IRC channel, it could point your friends to the IRC channel. If you were posting a lot on a specific message board or wiki, it could tell your friends that's what you'd been up to recently.
