This may be true.
But I use wikipedia for mathematics and then things like geography and history. For the former, it works very well. For the latter two it seems like it's not too bad.

The Wikipedia is no different. But it still allows the interested-amateur to do a breadth-first study of a topic without drilling down into a whole book. In both cases, the reader can't assume that she has seen an unbiased (whatever that means) story. But she can glean enough facts to be less ignorant about the topic than before.
Also, you would hardly ever see edit wars on math topics, but they happen all the time on politics.
