I love that this is free, simple, and easy to use. It's visually stimulating because it ranks everything with large avatars as well as the profile name. There is a way to export all the data as well so it's great to give to my boss to show her where we stand and who is influential in the market.

I love SocialRank's ease of use. Easy for anyone to get started and see their top followers, most valuable followers etc. and create lists and export data.
