Honestly I wish people stuck with good old forums. There's forums for everything out there, in every niche, gaming, modding, hardware, cars, boats.

Every single community you can think of has likely a great forum out there, easily readable and searchable, where discussions on single topics last _years_ and go in extreme informative depth, the kind of depth that no platform like HN/Lobsters/LinkedIn can ever dream of.

The closest surrogate we have are issue trackers (like GitHub) or mailing lists, but even those offer such a poor UX that I can't but wonder..
