True, but the root problem is in education. Our schools are passing out "social media douchebag" degrees left and right - we can expect nothing less.
This is only partially tongue-in-cheek. The balance of information systems operate on trust, just as economies do, and eroding trust at the institutional level is a bad sign.
As much as I like to make fun of the douchebags, I have to admit that there is some merit to the idea of Twitter as an opt-in marketing channel or a character-limited version of Google Reader — at least those use case are useful to some people. The original Twitter, although authentically social, ranged from boring (I don't care what you had for lunch) to frustrating (you can't have any meaningful discussion in 140-character chunks).
