There are a couple of blogs I read that get good comments, but most either do not or have the comments closed. The commonality between the few with good comments section is that the topic of the blog is relatively niche and the commentors tend to have deep subject matter knowledge. It's worth noting one major exception to this pattern: Marginal Revolution (https://marginalrevolution.com/ https://marginalrevolution.com/) is a very general blog, has a large readership, and still gets good comments on it (a lot of trolls too).
