This week is my 4th year on Twitter. To "celebrate" I put my account through several of these Twitter measuring tools collected at Social Media Examiner: "ways to discover more about your audience with social media."
I appreciated Followerwonk's details about the longevity of accounts I follow and that follow me. Very few newbies on either score, in fact this was one of the only results that wasn't a bell curve.
This bears out two Twitter behaviors I am aware of.
1) I have always been hesitant to follow accounts that don't provide high value (because, why?) and
2) developing the instinct to provide high value on Twitter doesn't happen overnight for most of us.
Among the information about my overall usage of the service, I liked these piechart details about who I follow (high value users who've been on the service at least 2 years, ppl who follow 500-5k ppl, and are followed by 1k-50k, and have these words in their bios: writer – author – media – creative – life – social – world – editor – global – business – founder – technology – design – women – tweets – entrepreneur – marketing – book – news – ceo – people – blogger – culture – digital – science – ideas).
