Three cheers for the Internet!

So, I'm sitting at work, having accomplished everything I need to do in thirty minutes and I'm staring at the clock. I have 7+ hours to kill until I can escape from the Job of Doom. What to do? What to do?
There's nothing on television and I've already checked my usual websites for updates. Read a book? Didn't bring one. Check out today's comics? Nah, I'm not feeling that. Maybe write something? Tried and, sadly, failed, but wound up killing an hour or so.
So, started surfing the web, at random and came across this interesting site on worldbuilding. Killed a couple of hours reading the site and following links and, well, now I have the urge to do some world building of my own.
Isn't the internet great? :)
