This pattern of behaviour hasn’t changed online either. I tend to connect with a few people and then interact with their groups through that connection. And because the business side of my personality is more outgoing than my personal side, my “few people” is actually quite a large number.

I would say that you are right on, here.

Social circles in social media do not seem to be much different to many facets in life – we venture out at first, but then we develop comfort zones, and the moment we become slaves to our comfort zones, we limit our potential for growth and development.

The development of social circles is necessary to some degree. We can’t mix with everyone all of the time and we have to make some priority decisions with regard to the people with whom we intend to spend most of our time. The development of social circles, to some extent, makes this process a little more manageable – we can’t talk regularly with the world, but we might be able to manage five, ten or twenty regular friends.

That said, I do agree with your comments about the need to change things up every now and then. You can learn some new things from regular friends and acquaintances for sure, but you can learn a whole lot more from entering new territory every now and then.
