We all know quite well that topics on this forum often ramble off into unrelated areas, which means that newbies (and others) looking for answers find topics which match their question, but in which they can’t find an answer because it’s buried in among dozens of posts which aren’t actually related to the topic.
On another Discourse site, where I’m an admin, I’ve begun carefully using the ‘split topic’ feature, which allows an admin or moderator to select posts from within a topic and move them into a new topic, giving it a suitable title. Discourse leaves a link in the original topic to the new one so that it’s apparent to readers what happened, and people who had participated in the original topic will get notifications for both the old and new topics (but can then suppress either one, if they really only wanted to follow part of the conversation).
I wonder if the admins/moderators of this site should consider doing the same, after making a suitable announcement to the users that this will start happening, so that people aren’t surprised when this happens to topics they are involved in. Thoughts?
