I don't get what a "social" grid has to do with what I stated. It doesn't have to be a social grid to have registered users. It can be a completely closed educational grid but the people still have to sign into an account to access it.
You seem to be so fixated on this social thing. We all realize that you have a business focused blog. We know this because of the name hypergrid"business" lol. But even if I set up a business standalone with hg enabled (as I did when I set up my 9 regions and my lindakellie product is basically a business and I was having a place for people to come get stuff) you called it a grid. It was NOT a grid. people had to make account on actual "grids" to get to my place.
Forget "social". Nobody is talking about that here. We are talking about what makes a grid. Also, every business has a social aspect to it.
