I've started thinking of this phenomenon as "blog driven design". It's what happens when you fall into the assumption that what bloggers are writing about is what everyone is (or should be) doing.

The problem with that is, blogs are a poor barometer for that sort of thing. Nobody needs to write new blog posts about tried-and-true things that are already plenty well documented. The more solid and stable a technology is, the less incentive there is for anyone to bother writing how-to blogs about it.
