Yeah, Reddit used to be my main source of information about more obscure rpgs because while videos are out there on YouTube, the search is really garbage and only shows the videos I want after searching it enough times and forcing the algorithm to realize that I actually want to see it. This is why forums like on Enworld and RPG.net are definitely the best method. No algorithm forcing you to only see stuff when it realizes you want to.

I think the main way I acquire new ttrpg reading at the moment might just be Goodreads' suggestions.

Secondary sources for me are things like different ttrpg communities in lemmy and mastodon.
