This is from Mike Connor's blog, one of the main developers on Firefox.
This is bugging me, and its been bugging me for a while. In nearly three years, we haven’t built up a community of hackers around Firefox, for a myriad of reasons, and now I think we’re in trouble. Of the six people who can actually review in Firefox, four are AWOL, and one doesn’t do a lot of reviews. And I’m on the verge of just walking away indefinitely, since it feels like I’m the only person who cares enough to make it an issue. Things I’ve raised in relatively private contexts have gone unanswered, and I’m growing increasingly cynical about our ability to ship 1.1 early enough to make 1.5 remotely viable this year. At the glacial pace of development we’re currently running at, I don’t see how the ambitious plans for 2.0 are going to be at all viable before late 2006. Maybe I’m wrong, but no one’s bothered to take five minutes and tell me that.
