Depends on the comments. I like the short, pithy multiple comments tied to highlighted text; those generate nice feels on my part with little thought involved. Short comments NOT tied to highlights leave me confused at times (“I have done the same thing!” Um, okay, which part?). And there are the occasional “this comment could have been an independent post,” which usually prompts me to suggest that (and I have done those myself, always referencing the article that put my train of thought into motion). As David P said, comments show I got people engaged.
