How Do You Find Reddit Topics Before They Peak?

By the time a post reaches the top of a large subreddit, the conversation can already be crowded. Do you watch smaller communities, rising posts, or repeated questions to spot topics early?

I watch the new and rising tabs in a few focused subreddits and keep a simple list of questions that repeat across communities. Repetition is usually a stronger signal than one fast-growing post, and it gives you time to contribute something useful before the thread is crowded.
