I agree and started putting effort into Mastodon. It took a week or two of filtering and browsing to find users and content but I've definitely found a more engaging base of content to interact with that is nice.
I was an engaged redditor who switched 100% to Lemmy and I do not feel quite satisfied with the comments and content.
I'll stick around, but I find myself on Mastodon and using Ground News more often.
Btw I have comments in my history of how frustrated I was about finding content on Mastodon, but suddenly it clicked after I spent a bunch of time on it. Not a raving endorsement but ultimately I do enjoy it.
Another side note, I was looking for some top users to follow and some have 10k followers, cool. Then I find some federated threads accounts with millions and realize how small we are in comparison. I know why, and I understand it, but it's truth that small user bases have less ideas.
I use Android, so Fedilab was the app I'm using.
I didn't want my feed to be an endless stream of news or other languages. So first I joined a smaller server, with a topic I care about.
Then I followed a few journalists, and followed tags I care about like cycling, my hometown, tech news relevant to me, and TV shows.
Lastly after I had that base of content... I went looking for people. When someone posts something I like, I check their other posts... do I like those too? If he's then I look at who they follow. Big accounts usually don't follow a lot of others. This is endless but really gave me a consistent group of people who I care what they think and say.
Not easy but worth the time over the course of a week or two.
Also I watched the #followfriday tag where people lost accounts they follow and why.
Also, look at the top accounts lists that exist. Threads accounts have millions of followers so it's a good bet it'll be good.
