facebook flurry

What's up with facebook? I've had an account for ages and done nothing with it the whole time because no one i knew was on it.... now all of a sudden in the last 2 or 3 days i've had like half a dozen ppl added, mainly old friends from school which is cool. Don't get me wrong, i'm not complaining ... bit of a weird flurry is all.
Here's my profile
