Well, I definately miss content. I don't have time to keep up with everyone I follow. The question is, what is actually important? The answer is going to be different for everyone, so we need many different options for feeds. Maybe you want to see the most popular posts from the past week, but I want to see everything with certain has tags. Maybe someone will come up with an AI that builds a personalized feed for you based on your behavior or explicit ratings you give posts. Maybe you just want to see things that have been marked as interesting by several people you trust. All of these things are possible, and more. If you have ideas, post them. If you can code, go build them.
