When I make new topics, I make sure that I read and reply to the posts by other members. It's about engagement and how responsible we are when we make new threads. If it's the same interest for the others, they'll also be back on that thread to converse.
Make use of the Telegram bot or any other ways to keep track of replies to your topics and posts, interact, and not just drop topics and forget about them.
I think it's normal to check the most recent threads that are made from time to time until it's no longer on the top of the board and everyone stopped replying.
