Choosing where to post
For beginner questions, r/learnmachinelearning is the natural first stop — it exists for advice, and roughly 49 new threads a day keep it moving. Asking the same thing in r/ChatGPT often gets it removed or lost among the 189 daily posts. Competition for attention differs a lot: r/MachineLearning has 3.1M members but only about 13 new posts a day — roughly one new post for every 231.5K members — while r/ChatGPT gets about 189 a day, one for every 62K. A strong, well-made post therefore has more room to be seen in r/MachineLearning; r/ChatGPT is better when you want quick replies. Rule sets vary: of the communities we have rules for, r/ArtificialInteligence lists 11, against 6 in r/ChatGPT, so a post that is fine in one can be removed in another.
Before posting, sort a subreddit by “Top” for the past month: it shows in a minute what that community rewards. 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.
