Choosing where to post
Competition for attention differs a lot: r/mlb has 3.1M members but only about 46 new posts a day — roughly one new post for every 68.2K members — while r/baseball gets about 170 a day, one for every 18.9K. A strong, well-made post therefore has more room to be seen in r/mlb; r/baseball is better when you want quick replies. Rule sets vary: of the communities we have rules for, r/baseball lists 14, against 8 in r/mlb, 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.
