That...seems cracktastic to me. 1-3 posts a day is not excessive and won't drown out anyone's posts, is the first thing, and second thing, it's likely to mean lots of unpleasant collisions ("I was going to post the last chapter of my story, but someone else just posted! This has happened three days in a row! I'm never going to be able to finish this damn thing!"). And I won't even go into the time-zone issues.
