I feel like kbin has the most Reddit-like feel in terms of browsing, although Lemmy has the advantage in terms of robustness and stability. Who else is hanging out in both spaces?
It's also nice to be able to easily follow Mastodon accounts across the whole Fediverse.
Even though I've always liked more to read news / blog posts and never found much appeal to Twitter-like services, I feel that maybe some specific accounts might be worth following, and having it integrated as part of the same service is very convenient.
