Why hash tag follows?
In my opinion hash tag follows would solve lots of problems. Users who want to connect for a short time only, say a concert, a sporting event or a conference could follow a hash tag. Communities of users could follow hash tags as a looser group (although groups would be good too). There would be no need to manually follow lots of users, no need for duplicated posts or retweets. So my request to Twitter is to implement hash tag follows. It would remove the requirement for pointless retweets, and would provide looser connections between large groups of interested users.
