I don't know what efforts have been made to publicize this forum, but obviously we need more people. There are more than enough cyclists in San Francisco to keep an SF cycling forum lively, and if there is already a general purpose forum for us then I don't know about it.
Perhaps the SF Bicycle Coalition would be willing to publicize this forum? It's worth asking them, as they've got thousands of members. Ditto for other groups with lots of cyclists. Craigslist has a bike forum, too, but far more primitive than this setup--perhaps that would be a good place to advertise as well?
