Wikiphilia
I've been obsessed with Wikipedia for the past ten years. Occasionally I find some good articles worth sharing and that's why I created the wikiphilia Twitter handle. Just a long stream of stuff that for one reason or another may be interesting.
It's also a bunch of friends posting links. Anyway, the tragedy is that there's 800 tweets but only 70 followers, so you should follow it now.
On a related note, this version of Wikipedia article for Warren G's Regulate was hilarious until someone removed it in 2010.
