Well, I posted an image yesterday asking for "real" feedback and I was pleasantly surprised that people are taking the time to really look at the image. It's clear that some people had improvements in mind but would probably have been too polite to write them unless they had been specifically asked. A few said the image was OK as it was, but this is just as useful because that's their true opinion rather than them trying to be polite. So I do think that whatever method used to get critique will be of huge benefit to those people who use it. I just hope that if it is a forum it will (a) get enough exposure to warrant its existence (b) take care of the bandwidth problem for users with slow connections. :)
