Choosing where to post
r/movies moves fastest, with about 186 new posts a day, so posts there get replies quickly but also slide off the front page within hours. Rule sets vary: of the communities we have rules for, r/movies lists 15, against 11 in r/horror, so a post that is fine in one can be removed in another.
A simple rule of thumb: ask questions in the specialised communities and share your best finds in the big ones, where they can reach the most people. Always read the rules in the sidebar first — each community is run by its own volunteer moderators. Our guide to searching Reddit explains how to dig through any of these communities, and the subreddit info tool gives you the stats of one we don't list.
