The Third Tuesday Measurement Matters #TTMM conference will put three social media monitoring and analysis providers on the spot and in the spotlight.

Each will be asked to tell us about a social media measurement challenge they set out to solve and how they did it. And then, we’ll ask them to look ahead and tell us what challenges they think must be overcome in the next year(s).

We have confirmed the first two monitoring and measurement providers who will be put in the spotlight: Radian6 and PostRank.

Radian6 was on the leading edge of developing an algorithm and index to measure influence. PostRank linked its fortune to the concept of engagement. Both have demonstrated an ongoing commitment to research and constant improvement of their monitoring and measurement suites. Clearly, they belong in the spotlight.

We have room in the spotlight for one more company. And I’d welcome your views about who it should be.

Which social media measurement platform do you think is on the leading edge of social media measurement? Which do you think have tackled a tough challenge and come up with an approach that is worth sharing?

Leave a comment on this post and help shape the agenda of Third Tuesday Measurement Matters #TTMM.

After all, if you want to understand the state of the art, why not ask those who are investing their money to explore it?
