What did we do without it?
... We used books and dictionnaries, we went to libraries, and met masters !
It was slower, but more human, and stayed longer in our memory.
(sorry don't want to be unpleasant... just a reflexion about "progress" )
Wikipedia is not the perfect tool.
As exemple kids and teens in school make a lot of "copy / paste" from wiki articles,
even without reading what they copy, and they think that they are working or learning this way ...
Saying that, I made donation anyway, to help to keep it trustworthy .
ISMLP and CONTREBOMBARDE deserve donations too !
