I agree there are a ton of articles saying "Use bcrypt." After Coda's post (http://codahale.com/how-to-safely-store-a-password/) it's almost become a meme. I don't, however, think that the people who say "Use bcrypt!" tend to explain why they say that.
I think the reason that this happens so often is that regular developers just don't care. But that's because they don't know why they should care. Given a proper explanation (and an attention span longer than "Squirrel!"), any reasonable developers would (at least, should) care.
