SociafyQ is an analytics tool that measures growth across numerous major social network presences, including Facebook, YouTube and Twitter, and includes tracking tools for blog keywords. Desktop data widget connections coming in a matter of hours.

All, I thought this analytics tool is especially relevant to your work. Please let us know if there are additional features that would be helpful, as we developed it to inform our own work (mainly on the nonprofit side) and thought it would be relevant to others. Cheers, --Dave
