1)Twitter has always been a fad...I'm extremely surprised it's lasted this long
2)Twitter, as a company, is in huge trouble...pick up any trade magazine and you will see how many CEOs and CXOs have walked in/out of Twitter over the past 18 months.
3)Twitter, IMO, is soooooo archaic...using # symbols and so many other crazy things to communicate. What year is it again?
4)Not sure what the value of Twitter is really. Do the majority of humans really need to "follow" someone every minute of the day? Not us working folk!
IMO Twitter will be as dead as MySpace by mid 2012.
