Back from 2000 to 2006, I was very active on photo.net. Then it went wierd, and very negative. People used to rage against each other over trivialities. I remember back when film was still commonly used how people would argue about how some particular emulsion was garbage because it wouldn't render purple flowers properly (due to UV reflectance?).
As a refuge away from this craziness, and with the purchase of a Leica IIF, I entered the RFF world. It has been a pleasant place, with people who can discuss love of these old film cameras (and new ones too), without someone always starting a war on why these all belong in the landfill since digital is now the true and only way and etc., etc., etc....
We do discuss a lot about rangefinders here, but there is plenty of activities regarding SLRs, medium format cameras, and even some large format. I view this site as a rangefinder friendly, general photographic information forum.
