Hi Rachel,
Thanks for a very comprehensive list of social media metrics. I work for a Company called Memcatch (memcatch.com), a social knowledge network and we use social media metrics to actually keep track of user activities among many other things. More specifically, we use:
-- Network Share Breakdown
-- Traffic Referrals
-- Viral Demographics
-- Viral proximity
-- Overall metrics.
Your list is actually offering a wide range of metrics from tracking the social media investments to actually understanding in detail the activities of different users so it's very helpful.
Thanks again!
