Twitter has probably always been my favorite social network, but I have been hesitant to invest too much time in the platform because I really had no idea how effective the investment was... until now! I'm not sure how long it has been live, but a couple of weeks ago I found Analytics showing up in my iPhone Twitter app and have since become semi-obsessed with Twitter Analytics.
I've been on Twitter for 5 years without knowing much about those who follow me and had to make a lot of assumptions. Now I know where people are following me from, how many people see my tweets, what their interests are, etc. I was very surprised how many people that follow me are interested in sunglasses. This is probably the most informative Analytics platform of all of the social networks.
I want go on and on about this, but go to http://analytics.twitter.com and find out more about your followers and tweets. I would love for you to comment and share what surprises you or what your favorite part of Twitter's Analytics platform is!
