Here’s one thought I had while reading : while agreeing with you on the macro view being the key here, i wondered how we make that concrete, to understand it – one example using twitter might be a view of all the people followed by the people that you follow. Followed of followed, if you will

services like mr tweet go some way to looking at this situation, but imagine the firehose we need to handle to get a grip on that (and to some extent it’s only really at what you’re terming meso level.)

Maybe we’ve blown away the Dunbar limit, or even just introduced a hereto impossible social connection type that augments the ideas behind Dunbar’s magical 150, introducing a new type of technologically managed connection. Like we use tech to augment our ability to do stuff (like remember facts, manipulate data etc) maybe these connections are of a different type than the ones originally described as “strong ties”?
