For some time now, there's been confusion about the multiple versions of Perl 6. Per Larry's wishes, Perl 6 is a specification of the language, and not an actual implementation. There will also be no "default" implementation of Perl 6. Pugs has been going strong for a while, based on Haskell. We've been talking about what to call Perl 6 that runs on Parrot, and Patrick Michaud worked with Damian Conway to come up with it: Rakudo.
It's a name the Damian has discussed before, and Yours Truly just so happened to own rakudo.org, hoping to be able to use it for something good and Perly. For a while, it hosted wikis that are now over at perlfoundation.org, and it's sat idle since then. I'm glad I didn't let it lapse, because now it can be an information center for the project. So far I've got a blog up, and I hope we can get more excitement about the project going as we post more details about the project there.
