The tech is awesome. A lot of what the user can't see is just plain sweet. This is mostly leveraging a lot of other people's elegant tools (CeleryQ, RabbitMQ, Mongo, etc.)
The front end is missing a lot of obvious pieces which have placeholders. It looks like Franken-App (or Franke-App's monster, if you prefer).
You're 100% right, to be sure. Nobody else will care the way that we do, but I know that I personally find it hard to revisit something later if it's really bad at first.
I doubt that what you have is crap. I also doubt that what you have inspires awe. You're putting too much pressure on this "launch." It's just the first of hopefully many public or semi-public iterations. No one is going to care anywhere near as much as you do about this. Just get it out there, consider it a success if you pick up a few early adopters, and iterate.
