Ad.ly analytics - when will ChurpChurp do this?

Ad

People know I dislike in-stream Twitter advertising.

But if companies are buying into the whole idea (and they are), why go on "word of mouth", when you can get nice shiny graphs and make sure your campaigns are actually getting the reach that it should be getting?

Check out ad.ly's analytics. Its quite interesting that they've built a model around charging for analytics - they upsell you for $9.99/mo, to get sentiment analysis, who is engaging with you, most influential followers, and more. For those that Twitter seriously, this might be useful. Of course, how does it compare with the numerous free services out there, say like Klout, etc?

SM sentiment analysis... JamIQ, Brandtology (Singaporean startups). Hot space? Or when will the fad pass...
