Social Activities Beget Social Objects.
It may be because I'm struggling to think of anything to write today but, having just read Hugh's latest offering, I was struck how I unusually couldn't agree with one of the points he made.
2. Social Networks are built around Social Objects, not vice versa. The latter act as "nodes". The nodes appear before the network does.
I think there is an intermediate element and would contend that social networks are actually built around social activities.
The activity exists before the network does (as I suggested when I wrote recently that you can't fake community) and before the social object. Indeed, those social activities may or may not actually involve one or a number of social objects.
What you should focus on is identifying those existing activities that you can facilitate and/or enhance by introducing your social object into them.
