The ActionMonkey team, in no sensible order. Names in parentheses are IRC nicknames.
Brendan Eich (brendan) – Mozilla’s superstar CTO. Invented JavaScript; wrote SpiderMonkey; still very active in its development.
Jason Orendorff (jorendorff) – Your humble author. I’m here to do ActionMonkey grunt work.
Edward Lee (Mardak) – Mozilla summer intern working on MMgc integration. Mardak’s here to do the grunt work that I’m too dumb to handle. 
You – I’m just saying. You could start pulling your weight around here. If you were so inclined. (Seriously: if you’re at all interested in hearing more, please comment on this post.)
There are many more people involved in this story: more Mozilla hackers with deep SpiderMonkey and XPConnect knowedge; the wonderful people at Adobe who donated Tamarin and are dedicated to continuing work on it in the open; the ECMAScript 4 committee, which is doing some other work that will soon collide with ActionMonkey’s world; and people from academia interested in fiendishly clever JIT techniques, security gadgets, and more. I’m sure I’ll write more about them all soon, but this will have to do for now.
Well color me interested, Jason. I started following your blog a long time ago and was nicely suprised (and happy for you) when you landed the neat new gig. Your topics are interesting and you write well. I’d love to hear more.
