Anyway, here's a list of some things I've, shall we say, stumbled upon:
-It's pointed me to some great pictures and artwork.
-17 cool magnet tricks
-Heartwarming story about a rescued greyhound
-A nice list of pin-up pictures of some lovely celebs
-Amazing pizza guy
-WikiSky, which is super cool
-Pictures taken at the exact right time
-Food porn (aka really delicious-looking pictures of food)
That's all I feel like posting now. I encourage you to try out StumbleUpon, especially if you're bored.
