Variously since then I have gone deep into some fringe but important-to-some topic and found hard-to-find sources. I've found it effective to collect and present this information in Wikipedia pages.
Like a few months ago I made the page for the Aircraft Reactor Experiment [1], the world's first molten salt-fueled nuclear reactor, built and operated with intent to make nuclear-powered long-range aircraft. I'm pretty proud of the page, and go back to use it somewhat regularly. Having the platform of Wikipedia inspires me to go the slight extra mile in personal research in a way that can be used by everyone.
Thanks Wikipedia, for existing.
