Harry Marks:

You used to be. You helped build Twitter into the global platform it is today. You were the ones who saw something meaningful in what others considered stupid and superfluous. You gave Twitter “at” replies and short links and hashtags and everything else that made the 140 character limit just a little easier to deal with. You were the true innovators – not them. But your services are no longer required. Please pack your things and go.

Worth a read.
