Well, now we know: Rep. Anthony Weiner used Twitter to send a lewd picture to a young woman. He then lied about it repeatedly before finally confessing.

It's stupid and inappropriate behavior, and the congressman has no one to blame but himself for this humiliating episode. It's not clear whether Weiner broke any laws or violated congressional ethics rules, but that's about the extent of positive things to say about him in this situation.

As before, however, I'm stuck on the inevitable "lessons about Twitter" media narrative. The headlines are everywhere: social media isn't private! What a dumb thing to do on Twitter!
