I don’t use mastodon, but yes, people are use to social media doing everything for you. Youtube is probably the greatest example of a service that will spoonfeed you content with little to no input from the user. My understanding of mastodon is that you have to know what you’re looking for to find content.
I can respect that, but also respect that people will find it empty and confusing, especially because it isn’t corporate, so there is no funnel to get the rolling. They have to be motivated enough to seek all of that information out and as much as people use social media, it isn’t that important to them.
