By the way, Habr - it's the same forum, only there instead of a question - narrative material in the form of publication, and below is the discussion (comments).As a novelty:
I'd do a sort of "branches" of the discussions of SINGLE ISSUES by different criteria/priorities (all indicators - consolidated from the current node, including all of "leaf" elements): the max messages per thread, max of the votes of the usefulness of messages, maximum likes, maximum number of replies from the professionals (from users with high karma), etc. (all depends on the orientation of the forum).
And next (based on the selected sort) write the branches of OTHER discussions with similar themes, problems and statistics (pictograms characteristics with digital indicators) as the current branch.
Thus, you can quickly find the answer interesting and similar discussion not only on the text but on all important indicators.
Let it be: a forum with a context-node type of navigation. ©2018, xmoonlight
