As a digital media strategist statistics are always going to get me a little bit excited - especially those pertaining to my own social relevancy. TweetStats is a neat little tool which lets you track - for free - your twitter profile statistics. (See examples below) It has great charts and word clouds to visualize and report on your Twitter activity, and although it is not as sophisticated as some of the proprietary tools available in the market, it definitely does a good job for analysing your own social currency when it comes to Twitter.
By the way - my twitter handle is @zara78 so follow me...and i will follow you!
