So basically not issues with Bootstrap, but an avenue for people on the internet to feel superior to a group that I'm not even all that convinced exists in any real quantity.

The problem with Clojure is those developers that just copy and paste code off Stack Overflow. Clojure is just so darn composable that it probably really causes problems for people out there with those copy-cats on the loose!

Don't understand why you're being downvoted. Good design for Company X does not necessarily reflect with what great design means for Bootstrap (I say this as a guy who almost never gets anything designed anymore). But it's a matter of budget reality for most people and companies that - it's really expensive to have competent developers AND competent designers for fledgling products. Perhaps there ought to be more money - and spread out better - in startups & product companies.
