Instead of resurrecting old posts, on Reddit/Lemmy you have people asking the same question again and again and again… On the cars subreddit you have the same “most interesting 5k$ car for sale around where you live” post getting created every few weeks, on a bulletin board you would have a single thread and people would just post new stuff when it comes out, the thread would come back to the top of the community’s front page and those interested would go check the newer reply…

I’m honestly surprised how many people that reply to me don’t seem to have experienced bulletin boards considering they’re still the place that “experts” hang on for most things (vs Reddit that is a better fit for enthusiasts that don’t want very technical info)…
