This is what I was going to post, seems to be about 90% of the activity on twitter. They seem to only care about the experience from the perspective of the haves, anyone else just isn't part of the conversation.
One of the main problems with Twitter is people sign up and don't know what to do with it - except message famous people. If Twitter prevents the plebs from shouting at the intelligentsia then it will make the platform even more irrelevant. The last time I used it, it was like talking into a void and that was with hundreds of real followers.
