If you’re participating in the Reddit boycott, note there is a federated alternative peeping its head out called Lemmy: https://join-lemmy.org/
Like Mastodon it’s ActivityPub-based, so you can subscribe to communities from your Mastodon account and have posts (and their comments, fully threaded!) appear in your Mastodon timeline. For example, here’s /c/composting on the SLRPNK instance: @composting
FYI no toot resulted from my reply here, at least not one I can see on Mastodon.
@drk @JacobCoffinWrites I do see a toot! https://m.twos.dev/@ben/110515181690714815
