vilakins | Facebook

I have joined Facebook, mainly because:

I knew two people on my flist were there (I have found two more)
Someone else with my name (who'd have thought it?) is there and I wanted to establish a presence of my own
It appears you can play games with others, not that I really have time till next month.

So, who else is on this thing, and what can I do with it now I'm there? What are the best and coolest apps to add to it?

Yeah, like I really needed another distraction when I should be finishing my finishathon story. :-P
