Where are all the new people coming from?

So I've noticed an uptick in the number of newbies around here. That makes me feel *old* and I'm only 25. I'm curious to know what has caused the recent uptick in newbies--how did you find out about 20sb?

From an oldie to the newbies, my best advice is to just jump in. It's intimidating at first, but most people love making new friends...and hence, new readers.
