If you don’t like discussion in the comments on slatestarcodex.com, and Scott hasn’t cross-posted a post to this site, the closest you can get to a better discussion structure like exists on LW with upvotes/downvotes, readability, etc., is on the the SSC subreddit. The culture of discussion on the subreddit has a reputation for being much more politically incorrect than Scott is himself, or what he permits on his blog. So, if you check it out, your mileage will vary.
