Do you go to Wikipedia a lot? Yeah, me too. I realize that for information on controversial stuff it can be a little iffy, but if I want to know know something general, it's a great place to start.
They have had the "personal appeals" banner up for several weeks, but today it was a picture of Jimmy Wales saying they needed the people who were reading this post to send in five bucks and they would be in the black.
My finances are in good enough shape, so I sent them $25.
If you use Wiki a lot - and for me it's in the top five sites I use for information, alongside imdb.com, The You Tubes, WolframAlpha, and the gosh darned Google itself - see if you have some spare change for these worthy beggars.
