Yeah fair points @Benjamin_D. I’d say from experience, the more actions you require a user to do in order to find more interesting/related content, the less engaged the users will be.
Have had several cases like this on other similar projects and having the ability for users to find more related content from the first page they land on significantly increases engagement and decreases bounces.
Especially for new visitors (generally the majority for a public forum) who we’d ideally want to be intrigued enough to join the community.
As for burn out, the idea would be that visitors/users would scroll until they find something interesting enough to check out. The top x results might not contain anything the user/visitor finds interesting, so this would allow them to easily look for more.
This is more so the case seeing, as far as I know, Discourse suggested topics aren’t based on similar topic titles/content. As you can see in the suggested topics for this topic, none of them seem very related to the subject of ‘suggested topics’. At least for me.
There should be more meaningful quality engagement for users who are in topics that they are very interested in also.
If infinite scrolling could be a concern that it could distract people from replying to a topic, another option would be a ‘suggest more’ button underneath the suggested topics.
