>Wikipedia has 51.1 million articles in 291 languages, is something like the 5th most visited website in the US, 10th in the world, and they manage to do this without running any ads. Can't we be thankful for the incredible human library of knowledge they've built, and chip in a few dollars if we are able, instead of complaining and telling them they should not accept donations?

But the donations don't go to the people who wrote those articles!
