From monitoring anonymous edits for several months now. It is not a net positive on the content side until I know which anons became decent registered users. So far, the gain isn't worth the pain to me, but I'm not the only admin and I'm willing to put up with it if the others want it and are also willing to put up with it.

I'll give it a year and if I still don't believe anons have significantly helped the wiki, I will strongly push for anon editing to be disabled. It was before (for most of WoWWiki's history actually), it can be again.
