Seems like there are several different information finding problems that people are trying to solve, and one super sticky type solution might not work well for all.
I would find it helpful to find a list or a gallery of sites that sell good "stuff" in categories, maybe alphabetical order by type, so for example if I wanted led rops lights I could find a couple of suppliers of ROPS LIGHTS that other ott members had tried without searching through several threads dealing with buying, using, and installing them.
On the other hand, if I were interested in how to do something like bleed the fuel line, I would want to read whole threads, especially those dealing with my model tractor, but would first want to know if Mr K and Vic had already made a video or there was a general article to read first.
So this argues for both something like virginiavenom's list as well as some super sticky kind of organization of topics, but it might be a lot of work to keep up.
I don't know how the search engine works, and threads wander, and lots of times at least I forget to put in keywords. That part of the menu is not very visible when starting a thread.
