That's an excellent consideration that I think comes with any drop-in functionality - ultimately there's nothing we can do to control the quality of the code/stylesheet/HTML/whatever else that we're pulling in. In Rails you can get into a special kind of dependency hell like this if you aren't careful, though my thought is that one of the most significant concerns with bootstrap templates specifically is related to the general size of the template itself (assuming it is correctly implemented, of course). What do you think would be a way to improve the utility of these templates, taking as read that developer time to replicate the functionality is likely at a premium?
