I have considered that! The thing I like about lemmy/reddit though is that I can follow a single RSS feed that dynamically mirrors the communities I follow, so I can just follow things natively on lemmy, and my RSS reader will pick them up.
I was trying to figure out if Mastodon can do this but I do not think it is a thing 😞.
I have some time to figure out what I want to do, though. Who knows, maybe I'll just add a few Mastodon hashtags. Thanks for the pointer!
