I'm a big fan of "ship early, ship often", but you have to set expectations properly. If something is not ready for prime time, you should signal that. Call it v 0.7, say it's a beta, label it as a "labs" product. Say up front where the known weaknesses are, and say what audience you want.

I also strongly recommend working with a small, carefully selected audience to begin with. Typically only a small percentage of your eventual audience will put up with the rough edges of a work in progress. Getting the average audience member involved early on is frustrating for both sides. You get a lot of feedback on things you a) already know about, and b) are intentionally avoiding for now. And they waste a bunch of time on stuff that wasn't intended for them.
