Just for the record, I much prefer Google+ to Facebook. On the positive side of the ledger, Facebook has brought into distant orbit a handful of long-lost friends. That is it for the positive side of the ledger.
Facebook seems tenaciously attached to its bad interface innovations. Facebook’s search function is laughable. The ‘be-friending’ central imperative is, for me, limited and not congenial.
Google+ has a slightly better interface, excellent search, and its users may access any other user. The latter advantage is very congenial to my open-ended approach to new relationships and incoming information. The serendipity factor on Google+ is by design central to its differentiation (as a platform) and its appeal to me.
There are ways to leverage Google+ which would make it an attractive vehicle for resurrecting the discussions that have mostly disappeared from my screen over the last ten years. Unfortunately, very few people I personally know are on Google+.
The upshot for my own usage is that the internet isn’t in the main a social space for me; it’s much more like a cosmic library.
