Nope, topics don't work. Telegram added topics and you can add them to the group chat, but it killed almost every chat that I have seen add it. What happens is people start conversations on random themes and this additional friction of posting to the right topic kills the motivation to post at all. Also, people start to only open topics they like in the group, and close the group if there's nothing to see in these topics. If there were none - they could find something interesting for them randomly, or answer some question, but they just won't find it because they only check topics they like. It also feels more strict, like a confluence wiki of questions/situations and you can't effortlessly chat about something.
