You acknowledge that most people probably have similar problems; the stuff their friends are posting isn't interesting, and also acknowledge that you don't follow along with your friends' posts.

You're agreeing with the original post. That is a sign that the site is useless as is, except as an echo chamber for you to post things you are interested in but nobody else cares about.

You're posting running stuff, and there's millions of people who are interested in running stuff, but instead of those running posts finding other runners, they find your friends and family most of whom aren't interested.

That's the problem with Facebook. This is less of an issue on Twitter where it's normal for you to follow whomever you want, not just friends and family.
