It seems that Wikia is not very willing to discuss when they will release the missing parts of answer.wikia codebase — if ever. Wikia's contact form a.k.a Special:Contact is more or less of an alias to /dev/null. It's a shame, really. In my opinion, it's important to allow the users to participate if they want to do so. Now all the users can do is provide feedback and make suggestions. Surely it'd be better if the users could just take a look at the source code and fix the bugs they've found?
I've probably said it before, but I'll say it again just to make sure: it's not my problem if you're running your site(s) on a collection of hacks and quick patches. I've already offered my help and I know when it's not wanted. I just thought that it would've been nice to have an open-source answers platform for MediaWiki (since WikiAnswers is not open source) and it would've helped Wikia too, allowing better internationalization and more bug fixes.
Also, Merry Christmas to my readers — have an open-sourcey Christmas. ;-)
