I think once there ia a larger volume of posts this may start to take care of itself. Since traffic is lower here, what my feed looks like is similar to `new` on Reddit. Once there is a lot more traffic, then all I should be seeing are the more popular items (assuming things work the way I think they do here.) So then it will all come down to whether or not the community upvotes quality items or not.
It won't be the most popular. It will be tailored based on who you follow. Only follow people whom you find interesting, and don't worry about what's popular. If I share all of your opinions, do you mind if you're my only follower, as long as I keep you interested? You shouldn't.
Yup! Whatever's most popular among people you like matters, but not overall popularity.
