I think what kbennet said is true...most people already limit themselves to one per day at most. However, I'm in favor of a one-per-day limit, just in case it helps. It might also encourage people to consider which of their works are most worthy of posting, ideally cutting back on the "test render of my new toy" type images. Very rare is the person who can crank out three quality images a day, anyway. I've come to like the new genres system, after initially resenting it, however, some people's understandings of those genres are strange. I recently looked for "Poser, Abstract" images. The vast majority weren't abstract at all. Just the same old figurative "airbrushed Vicky" pics, for the most part. Oh well...
