So which tool do you use to manage you social media “value” and why?

The three I most hear about are Klout, PeerIndex and Empire Avenue - and they’re all starting to look the same.

While these sites are rapidly being adopted by people in the digital marketing world, will there ever be a time they’ll be used by anybody with a facebook profile?

Are these kinds of tools the first step to people managing the sale of their own data for advertisers to better target them with the right products and services?

Or, like Empire Avenue, are they just another example of gamification and a bit of addictive fun?
