Allow edits to the post, or allow the author to append short updates to it, or something else, but I think the rate limit is an interesting thing and worth sticking with at this stage. It's a principle that once you break would be hard to reestablish. The main risk is that slow posting probably means slow growth, and that is a reason to add some kind of exception -- but try to make it limited it, imo. Maybe new users can make secondary posts, and as they post more and connect with people, you guide them somehow towards 1/week. Sort of reversing the traditional pattern that new users might need to be rate limited when they first sign up, instead what you want is for established users to post slowly.
