Valuable knowledge about IHP is spread over plethora of sources: the Guide, IHP Slack, IHP Gitter, this forum, but also StackOverflow, reddit and of course blog posts by IHP users, some of them being linked in the Guide's recipes section.

How about collecting posts from all of these instead, per API, scraping or a way for people to submit their stuff? Comments as sub-items, but also searchable.
