Almost exactly 2 years ago I started micro-blogging. Back then I signed up for Twitter, Pownce, and Plurk accounts. One month later I concluded that I really liked Twitter and that Pownce and Plurk were annoying. A few days later I discovered Identi.ca - a FLOSS version of Twitter and decided I would send frivolous tweets to Twitter and tecnological dents to Identi.ca. Then, a little while later Pownce was taken off the net. So what has happened in the intervening years?
