When I'm not sure if I like a website or an application I think of it as a persons who is talking to me. Sometimes that helps to make up my mind.
When I look at twitter, there is a multiple personality talking to me. Or somebody who is just namedropping, without actually saying anything. The more people you follow, the less communication is happening: you don't see your real friends anymore you hardly care about what all these guys are saying it's just noise going on...
This turns twitter from a communication to a publication media - the same antisocial stuff as your old tv station.
This tells me
- it's in the responsibility of the user if a media is an information-, publication- or communication-media. That's quite a lot of power and can also influence business models.
- I will unfollow all professional twitter users; they just waste my time for too little benefit.
