Law Firm Networks

Nick Holmes over at Binary Law has posted about the number of Law Firm Networks on Facebook. I'm mildly surprised that there only appear to be 4 networks for UK Law Firms. Although having read the Facebook help on "Networks" I can see why;

"You can suggest new high school, college, work, and regional networks from the bottom of our Suggestions page. Facebook regularly reviews these suggestions, and adds new networks when appropriate."

Does when appropriate mean, when enough people request the network? I suppose the other thing to remember is that there will be many Groups for UK Law Firms, a search for Clifford Chance for instance returned 27 Groups.
