I thrived on daily reading of a few multireddits, which are specific clusters of the same subreddits, as my default view; I only went to the general feed for all of my subscribed communities every once in a while.
For example: https://old.reddit.com/r/YouShouldKnow+LifeProTips+dataisbeautiful
Is this possible on Lemmy?
Indeed! But since it’s all ActivityPub there is actually (limited) interoperability even with those platforms. Mastodon users can post to Lemmy communities for example.
