Rich Karpinski makes an interesting point,

Do telecom service providers own anything equivalent to a social network’s social graph? At first thought, we’d say no, though as hinted at above call detail records are information-rich and enable telcos to track (and bill) for small actions at an individual level.

How service providers deal with the power of the Web social graph is a key competitive question moving forward.

I think the difference between service providers, and places like MySpace, is you voluntarily put your information on MySpace for the world to see. That’s not to say that the telcos won’t use their social graph information for internal use and analytics.
