Not trying to sound mean, but I think the world's number one free encyclopedia site asking for (not "begging for") donations once in a while (once a year, intermittently) with a simple block of text isn't something people should be annoyed of so much as to figure out ways to block it. Think of all the benefits they mean to people, and indeed they run an enormous infrastructure and several sites which are pretty much funded only by donations, so they sure need to ask their (non-paying) users/visitors to chip in whatever amount of cash if they can and if they feel like it. You would do the same if you would run a global, advertisement-free website like Wikipedia for the public's benefit. They aren't much different than DonationCoder, they are just involved in way bigger goals.
