I don't want to discredit Patrick, far from that. He's done some amazing work. And the same counts for Johnathan. On top of that, it's always nice to catch up with either of them if I run into them at a conference.
But it's worrysome that a project almost comes to a halt if a single person, for whatever reason, is suddenly unavailable. That's not a sign a project is anywhere near the state of "mature". If I were an IT manager of a company that may consider switching to Perl6 at some time in the future, I'd take notice.
