Don't you see a problem right there? In my opinion, it should at least come bundled with an optional style (the old Bootstrap2 style would be fine), so that we could at least use it for fast prototyping. In its current state, it's kind of useless since I'm gonna need a designer from day 1 anyway, because it looks terrible by default.
