I just started using Mastodon. It’s been around 10 days or so. I am already having a lot of good engagement there. I guess “no algorithm” works best for me. I used to get bored of scrolling twitter or even reddit within 15 minutes or so. On Mastodon on certain days I can easily spend 45 minutes or more.
In my case the algorithm bored the heck out of me. I stopped using Facebook since 2015. Even the youtube algorithm has started boring me now and I am happy with newpipe.
