AP issues staff guidelines on retweets, no ‘personal opinions’ allowed or implied | Poynter.

I feel like this is another step by which one's personal life and professional life is becoming more and more intertwined due to social media. I'm guessing since Twitter is relatively new, most of these AP employees signed up for Twitter while working there. But what happens when someone who already has a Twitter (or Facebook, or a blog) gets a job with the AP and now is subjected to their rules? I had to make the decision at one point whether or not I should accept friend requests from people I work with. I understand that with some jobs your public persona is important, it's just interesting to watch.
