The content is really bounded by tech stuff, but I guess that's due to migration being important for tech-savvy users. It is true that appending "reddit" to search queries and following the results is still inevitable (but hey, libreddit and teddit still work). But vibe is completely different, very organic, very active, I like it a lot. I think there is a lot of potential in this feeling of authentic communication. Let's hope it grows.
Lemmy is much better replacement for Reddit than Mastodon is for Twitter.
Glad to be of use!
