Like most popular social media sites, you usually won’t see very valuable discussion in the comments, at least in my experience. It’s mostly for people to post news, research, and so on, and follow the big names or organizations in their field.

Most of the valuable information is diffused via posts but I do put a bit of time and effort into trying to filter out all the crap posts like memes, the faux inspirational stuff, self-aggrandizing nonsense, etc.
