I don't donate to Wikipedia.
I do rather like looking at the editing history though. There is a lot of vandalism of wiki pages going on, it pays to be aware of the lengths people will go to in order to disrupt. However, while Wikipedia is good as a starting point for some subjects, it depends on the veracity and integrity of the authors.
The Jack the Ripper museum has an interesting editing history.
