hello sfdorkbots,
back in london my friends earle and kake run an Open Guide to London which has been on the dorkbot circuit a few times. http://london.openguides.org/ - a wiki-based city guide, with spatial metadata which you can get in RDF.
http://sf.openguides.org/ is an SF one i set up while staying here, tinkered with to add geocoding and a map service. i'm really a tourist though and don't know a community of interest like the london one had - a lot of perl hackers with shared interest in real ale and sushi. so i would appreciate contributions to it or commentary about it... i am aggregating the metadata in a spatial model useful on local free wireless services.
