Liquid threads are kind of better, but still not ideal. My main concern is that this still requires you to go to different pages, some are difficult to get to (have to know it specifically or get refered). For example, if someone were to ask a question/start a discussion on certain type of targeting etc.
Personally I think a forum works the best, as it can break things down into different categories and list everything out in a manageable fashion.
The Facebook group is good, but it lacks the community involvement, in my opinion.
Google+ seems cool, but I can't sign up for it with my Google Apps account..
... and who uses yahoo? :P
It will take a while to get used to. But there is no need to diff the discussion pages anymore. Neither convert local times to UCT every time I write something. Nice work.
I have only one complain. LiquidThreads is polluting the Recent Changes page.
Ultimatebuster: With regards to a forum, personally the problem I would have with a traditional one, is that conversations are often with regards to a specific concept that either has or should have it's own wiki page anyway. The tight linkage between pages and talk pages encourages cross-pollination between the two sides, with discussion inspiring wiki pages and wiki pages inspiring discussion. Plus, I feel that the categories that would be created in a normal forum would be too broad for robocode and cronological sorting within such large groups too limiting.
Maybe it would make sense to have a page using liquidthreads which is specifically for asking questions when a specific page is not known? Perhaps do something like prominently link it from the main page, or even embed it?
Well, although beginners may not know, but I believe with our not-so-large community you can ask questions on almost any talk page, and if it seems inappropriate, someone will move the conversation to the right place. I really think we should have a bot that post welcome message to user, since IIRC it tells that you can ask question on your talk page.
