If there is one change I would like so this is not a pure clone of Twitter, it is to make it visually obvious who I follow vs not follow (e.g. via colour, typeface, bold, etc.). Then I can more easily follow the non-follows! I tend to follow people who engage and contribute constructively. I don't belief in just "following back" for its own sake and building numbers. Curation of your inputs is OK, indeed necessary.
An excellent idea! if there's a poll, I vote yes!
