Conrad Schneiker recently gave the Perl 6 community a gift by loading this new Perl 6 wiki full of content. The wiki itself runs SocialText software written in Perl 5 and hits a nice sweet spot between being featureful and easy to use. I recommend trying it out, and plan to use it frequently myself.
This wiki is still young, and as Andy Lester notes in the comment at the bottom, it would be useful to break up the front page content into several pages. It's a wiki, so feel free to jump in and help with that!
Update: I went through and overhauled the front page and site structure myself, so the front page is simple new, with some embedded Perl 6 news. Of course, it's a wiki, so you can further refine it as you like.
