To be fair, if you want content on Mastodon, you have to actively go out, find people, and follow them. After you get past that Step 1 of signing up, your home page is empty. There's no algorithm that automatically deposits content on the main page. You have to do a little bit of work to get anything. As you say, doing this work is not that god damn hard, but sadly for about 80% of people (maybe more), this is an impassible barrier.

On the bright side, once you do get past this barrier, none of the Mastodon content that you are getting is from that bottom eighty percent.
