Hi all.

Does anyone know of a hosted version of Yahoo! Answers (or Stackoverflow/Superuser) that I could integrate with my site? I know that there are some open-source implementations (see http://meta.stackoverflow.com/questions/2267/stack-overflow-clones?page=1&tab=votes#tab-top) but I'd rather have some hosted if possible.

I know there is http://stackexchange.com/ as well, but I really want some tight integration with the rest of my site.

Failing that, has anyone got any experience with the open source versions? Some of them look a little, erm, unfinished...

Thanks.

Neil.
