For me, the content created by communities that is exclusively available on that site is really helpful to me. If possible I would definitely try and archive a few subreddits and write something to search and access it offline (sorta like https://en.wikipedia.org/wiki/Kiwix but for reddit).
I’ll probably have to reference the site for some time for information that is only on Reddit. It’s a bummer but realistically expected given how massive of a site it is and for how long, it’s unavoidable for most and that’s okay for now.
