I haven’t thought lots about Twitter recently. I haven’t been using it – or so I thought?
There have been lots of reasons for this. Firstly a busy business and family life reduces the time I can devote to Twitter, which can be a distraction.
Secondly, I find that once I’m following more than a few hundred people it becomes difficult to relate directly to most of them. British anthropologist Robin Dunbar theorized that “the limit is a direct function of relative neocortex size and relates to all human relationships, not just Twitter. If you have a respectable neocortex you may even be able to relate to as many as 150 people.

Like many people that hear of Twitter, at first Andrew thought of it as a waste of time, and wondered what all the fuss was about.
