Wikipedia - use it or abuse it?

@Wikipedia is one site that always gets my support. It has all the world's knowledge in one place, compiled by experts in their fields, and relatively free of bias, though I am not well positioned to judge how much Western/Californian influence goes into it. It is free of advertising, which is a distinct blessing on a web more and more dominated by that menace each month. But it does require some financial support, therefore each year I make a small donation to their appeal,  Support Free Knowledge!

This is very much a case of use it or abuse it!
