Way too much time on forums, just not so much on RFF anymore. I used to try and keep up with Topica, Delphi, Nelsonfoto, Photo.net, Ace Forums, BestStuff, Yahoo, MSN, eBay groups, various camera repair sites, The Camera Collector, Rangefinder Forums and a few others, but had only so much time per day. I had 46 groups in Yahoo alone so I've culled most and only do Kar Yan Mak's repair site (very helpful), The Camera Collector (friendly folk), Photo.net (often too many pompous or condescending people but interesting cameras), and of course RFF (one of my favourites but I don't post much anymore as everything seems to be Leica or Zeiss these days). Still spend about two hours per day between these and of course, eBay.
