>the quality of posters and posts in general tends to go in waves. At a high point, resulting content is still of top notch quality, but the average and low points are both quite pathetic. Importantly, "aimless" qualify them quite well.
You need to let people post if you want them to learn how to post.

This is a little off-topic for the thread, but a related problem I've seen in some other imageboards for a long time: because people are so picky about posts and lash out at anyone who's not acting in the exactly correct way, people don't have the means to learn how to post. If you're immediately punished for not doing everything correctly, it's going to deter people from even trying, let alone honing their "imageboard social skills" and OC creation skills through practice.
