So... Yes and no. Yes from the perspective that there can be a feeling of FOMO and some entire communities on the big instances that see a lot of activity that you can't access here. I use slrpnk.net to see those. But the thing is when I log into slrpnk (which is VERY well moderated) it doesn't take me long to find some horrible awfulness that has found a platform here in the fediverse. Genocide denial, alt right bullshit, authoritarian communist bullshit (which isn't even communism, GODDAMMIT), it's all out there right under the surface across some of the biggest Lemmy instances. Its bad enough it makes me not want to log into log in to see what's going on on Lemmy most days, so I don't. I probably check beehaw about once a week and slrpnk about once a month.
I'm very excited to see where sublinks goes and if they can put together a version of a federated link aggregator with moderation tools that work
