This final note today — either the secret to good human resources management at companies everywhere or yet another indicator that Facebook is nothing more than an enormous time-suck.

There’s a study out in the Journal of Applied Social Psychology this month looking at whether people’s profiles on social networks — by which they mean Facebook — can predict job performance.

The short answer is you bet they can. Which leads to this, at the bottom of the study: 1) They say they need to do more research to fully validate their findings. And 2) I’m quoting, here, “consideration of legal risks should be fully considered.”

Yeah.
