TheServerSide.Com has a post up that references what Don Box and I wrote, and there are some comments that you might find interesting. And not just because of the nice things that Rolf said about me.
I agree with Cameron when he says:
The difference in the Java market is that the community is made up of peers. It is _not_ simply a vendor / customer relationship of convenience.
This was what I was trying to get across in my summary post around JavaOne. Though we've made some good progress in the community space, we're still not very open from the design side of things, and that's a challenge we should take on.
