What is the number of “informal groups” in the US? One proxy might be the number of Usenet groups.?

Question by brentc123: What is the number of “informal groups” in the US? One proxy might be the number of Usenet groups.?
I am trying to get at the number of “informal groups” (affinity-based ad hoc groups) in the US. One proxy for this data might be to find out the number of Usenet groups… but that’s an international number. Also love to get a guess at the average number of members in each group. Think book clubs, bowling leagues, hiking and fishing clubs, etc.

This is a treemap of the Usenet newsgroup discussion community space generated by the Netscan system at Microsoft Research. This map represents a year of message reception by all Usenet newsgroups that were collected by the Netscan service. The area of each box is proportional to the number of messages that newsgroup received. Bigger newsgroups create bigger boxes. Color maps to change from the prior year, green indicating growth and red for decline over the prior time period. The original sized image shows significant detail. The treemap tool is available for free download from the research.microsoft.com web site. It comes with an Excel plug-in that allows users to generate their own treemaps with any data they can get into a spreadsheet (that contains a properly formatted hierarchical data structure). Your mileage may vary. Netscan can be found at netscan.research.microsoft.com.
