This is awesome. Yes, there are some usability problems, a few bugs, and tonnes of missing features, but I already like it better than Basecamp. I started dev on a product like this a long time ago, when Basecamp was relatively new, but I didn't complete it. I was going for a Redmine-esque feel and that's what I get out of Ubercamp.

Keep it up. I hope you will stick it out as you have some big competitors.
