I am creating my own new blog.<p>I removed the comments system from it, because in my past blogs, comments were rarely useful. If a post is interesting enough to need comments, it usually ends on social media anyway, where people can comment there (like HN, Reddit, Facebook, and so on)
Because platforms like Hacker News and Reddit are far better tools for commenting on a subject than any comment system will ever be on a blog.<p>SSO, threaded comments, reputation/karma/pruning, etc. are features that seldom exist on blogs.
Because a) they don't care [Swartz] or b) they are worried that having comments brings down the quality of the article. [Svbtle] [1]<p>imho, the latter reason is idiotic. It's the quality of writing that determines the quality of comments. (I have written quite a few blog posts on the topic, as I sorta gained my fame/infamy through blog comments)<p>[1] See Medium's reason for dropping comments. <a href="http://techcrunch.com/2012/12/21/medium-becomes-a-more-full-featured-writing-platform-adds-stats-and-explains-lack-of-commenting/" rel="nofollow">http://techcrunch.com/2012/12/21/medium-becomes-a-more-full-...</a>
Sometimes it's for legal reasons. For example: In Germany, the website / blog owner is liable for any kind of content that is shared through comment systems. You have to continuosly monitor your blog for any comments that might contain illegal material.
