Community - I agree with Twee you are killing us with kindness, although your intentions are good.
These Community posts should be placed in a highly visible but separate, designated "sticky" area that also enables other contributors to add helpful sticky information, once they have first been presented and cleared by Community, of course. !
Once they are old or out of date or no longer applicable, they could easily be removed, either by yourselves or the original poster. That would prevent them clogging up the unanswered post section.
