Hey, I may have listed this website before, but as I've researched that a Twitter Wiki seems more valuable than my other services, so here I go. It's built off the MediaWiki open source, and I totally intend on making a better generation for it. However, the popular "Wiki" format seems the best way to do it, so I decided to build it off MediaWiki. It's with the original Wikipedia design, however I do intend on changing it to something a bit more "twitter-ish" in the bright blue colour scheme. http://www.yu.mu/ Reviews please, before I get it going.
What exactly are you wanting us to review? The theme is default, I don't see a wealth of content. Maybe once the site is completed I will be able to give a better review.
