Another, rather dangerous, side to this is the shrinking scope of medium format. In reality there's only one brand left, Phase One. To call the current Fuji and Hasseblad cameras "medium format" is little more than a marketing ploy. Their sensors are a mere 26.6% larger than the "full frame" sensors (sensor diagonal). While they both offer exceptional image quality, that is probably more due to great lenses than to sensor size. And just for comparison; a "full frame" sensor is 53% larger than an APS-C sensor, more in the case of Canon.
In reality, the border between "full frame" and most current medium format cameras has become very fluid. Apart from P1, photographers choose between them based on brand preference, lens choice and economy rather than image quality. The question then becomes if a forum like this can survive on the users of mostly one brand plus vintage backs that will become increasingly difficult to service, and those enthusiasts who use medium and large format film. Fuji and Hasselblad users may still stay here, but as has been mentioned before, those Fuji users often also shoot other formats, like Fuji APS-C.
What I would personally have wished for is categories based on format/sensor size. However, most photographers seem to be brand enthusiasts, so I'm not sure if that would gain much traction. Additionally, differences in lens mounts etc. might render such a suggestion impractical.
