I don't, personally, see this as a huge problem. It will encourage news organizations to use hard passwords, to rotate them regularly, and to not share them. It's easier to say that than to do it, but when someone tweets as part of their job, that's what should be done. As for undermining the credibility of a news source (insert cheap Fox News joke here)... I don't believe it. While Twitter can bring very rapid information, there's also a very easy and quick way to rebut fake postings from an account. Did anyone REALLY take those Tweets as gospel regarding the health of the President? I guess some might, but those people are nuts and I don't think that Twitter is their problem Ed O.
