I think the "release often" philosophy is a good one, but too often and you just open yourself up to "this doesn't work, that's wrong, this is broken etc"
I think knuckle down, code a bunch of good stuff then show it off. Of course you'll still get the complaints, but it'll be a lot clearer to a lot more people how it works and the potential it has.
All that said, all they've shown us here is a very simple demo, we have no understanding of the underlying message passing protocol and its robustness. It does look promising, but looks of course...
