There are a lot of links on this site to Wikipedia. I donate $100 a year, so don’t see this as an issue. I would also use it as a subscription service. All this even tho’ some of their contributors are willing and able to subvert the integrity of the site in general to make biased contributions on politically sensitive issues. In general, however, I find the site to be a good first stop for most topics that aren’t political hot potatoes.
If you use Wikipedia, you owe it to yourself and others to donate.
