Hi everyone. I just joined the list; this is my first post, but I've been following the developments with interest.

I just learned about another promising MW parser, from the AboutUs guys, and thought I'd share it here in the list:

Kiwi: A Fast, Formal WikiText Parser - http://blog.aboutus.org/2011/01/31/kiwi-a-fast-formal-wikitext-parser/

Cheers,
