I find that the quality of content is totally different here. The level of engagement is similar for me. Most of my posts and comments get about the same engagement as I saw when I was on Reddit, and often a better quality. There are some niche communities that just don't exist (yet), and there are some crowdsourced communities that don't really transfer without huge numbers of people (things like AITA, mildly interesting, oddly satisfying, etc.). I do miss some of those aspects, but the interactions and information here are just better and less troll-y.
