"Reposting Tweets is not Real Journalism"

As Tiffany Anderson noted in her recent post, protestors of the political situation in Iran are increasingly using social media to spread awareness.

It’s interesting to note that traditionally professional journalists are using the same social mediums in their reporting. While some may debate the journalistic merit of Twitter feeds, with this topic in particular, audiences depend on social media for the most recent turn of events. One particularly popular source is Andrew Sullivan’s blog at the Atlantic, which aggregates news snippets with little additional written editorial. It’s a far cry from the lengthy descriptive articles found on NYT or WSJ, but several people have referred me there for the most up-to-date information. As far as journalistic merit, the pieces that are posted are often factually unvetted (by Andrew's own admission), are distributed with one or two lines of commentary, and are said to be skewed toward the blogger's political perspective.

So, concerned citizens of the world: Is this "reposting of tweets" enough to qualify as “real journalism" or something else? And does it matter, as long as the world is informed?
