There is another aspect to this, that is that I try to keep up actually looking at people's work. I know that I feel if I've put lot of work into an image, I really appreciate it when people stop by, and comment on it. When the galleries are flooded, it is impossible to keep up, how much I really want to. When the amount in the galleries are limited, there will be a fair chance that people's work actually will get noticed, - and commented. Which in all makes for a much more social place. :)
