I'm pretty sure there's a market for this, I was in talks with a major Chinese company hiring to achieve a similar service for brands on Weibo (Chinese Twitter/Tumblr mashup). But it sounded kinda scummy to me and I dislike social media so I bailed.

They seemed to have a pretty manual system already up and running and were working on automating a lot of the churn, not sure how well that would translate to English markets, but I'd bet some companies would pay for it to save themselves hiring 'that social media guy/gal'.
