Ed,(posted 8215 days ago)I'm curious as to what the demise of free services on www.greenspun.com has to do with the sad story of ArsDigita (for which there seems to plenty of blame to go around). I seem to recall that the home page for greenspun.com used to say that it and its services were hosted on a server cluster that was part of some experiment at MIT.
In any case, the move to photo.net is probably a good idea. As Dan Smith suggests, it may help introduce more people to B&W photography. It seems that a certain amount of consolidation is inevitable that as the web matures.
