I use Wikipedia regularly, and apparently it’s costing them a bundle to keep the servers going. While I have on occasion had issues with the way they run things, overall this is shaping up to be a humanity-changing effort. So I slid them a couple of bucks. If you use Wikipedia a few times a week, you should too. They’re looking for big donations, but if everyone voluntarily pays just a little we get closer to the utopian ideal.
