slava @ rethink here. Thanks for the vote of confidence, and sorry for the poor experience. The product is improving very quickly, and we decided to trade off format stability for speed of development until we hit 2.0 (at which point we'll freeze the formats and put more resources into backwards compatibility).
This latest release has actually prompted me to check it out. I had been meaning to but hadn't found an exact usecase for it yet, now I'm just going to try to build something with it, though I don't know what yet.
This kind of dedication to it is definitely what makes me want to check it out, you guys are doing some really great work on it.
