Man! Curebit is definitely very wrong, but all those abuses just don't make a pretty read on my twitter feed. I am gonna unfollow DHH. I respect him a lot for what he's achieved, but all that profanity leaves a very very bad taste.
Personal learning: never abuse. Those words mean nasty things.
Don't understand the downvotes at all...
Curebit's case sets a very ugly example. Profanity in the same sense sets a very ugly example for younger minds, especially when coming from such a well respected entrepreneur.
