I doubt anyone will listen to me at this point, but that was not an official announcement. I wrote that email to preempt a policy decision by the Gentoo Council that would have negatively affected the goals of our nascent project. A consequence of doing fully open source development is that with the exception of issues involving the security of our infrastructure, all of our internal emails are public.
Anyway, the official announcement will come later. We are still working on becoming organized. I also probably should register on slashdot.
