This is how I feel as well. People always say that Mastodon will never replace Twitter because it’s either a) too hard to sign up for, b) no enough people on using it. However, since it’s federated, I feel the easier to find people and posts that are more akin to my interests on there. I just joined a midsized software dev focused instance and followed a few tags for my hobbies and my experience is great. It almost feels like Reddit in that way.
