Admittedly the thing I miss most about Twitter was the sorting algorithm. Creating an interesting and engaging "experience" with Mastodon has been challenging, but I'm getting there and it helps as more people join.
My advice to any new Mastodon users: spend maybe 10 mins at a time searching for good tags and users to follow. Give it a few days (maybe weeks) before you can expect to see a feed as rich as Twitters. Endlessly scrolling as a brand new user is very unproductive.
