I think that GN got a grant of some kind to set up local GN webpages (not physical groups) and support them for a year. They appealed for volunteers to edit the pages, and I was one of those who managed my local page. Several other pages were set in up various areas, but a lot of the country didn't have any coverage.
One of the things we were supposed to be doing was canvassing locally to get local businesses to sign up on a free list, with the option of also buying advertising space. That took far more time and chutzpah than just editing a chat page and creating interesting snippets about the local area. We were essentially trying to sell advertising. I wasn't any good at that.
When the year was up, most of the local editors left. A few continued for a while, but I don't think there are any local pages still functioning. I wish GN would remove all mention of them.
