It's taking some time to get over the withdrawal, but despite the fact I really liked some subreddits, staying off has become the best internet habit-related choice I've ever made. The low signal-to-noise ratio you mention is one big factor. The other is I needed some obstacles to ease of use to make my choices more deliberate. I have found alternatives, sure. But now I spend maybe a tenth of the time on social media that I used to when I was redditing every day.
