I like the idea, but I don't think there's a need to reinvent the wheel. That is: I think it'd be more useful to build integration tools for existing products, than to force people to use a brand new task management app. If they like their bug-trackers and they like their task managers, why not just build a way for those existing products to talk with each other?
