It depends on the subject imo. The comments on political articles are rarely good. But the comments on technical subjects can often be good. Compared to HN, Slashdotters are curmudgeonly about startups and consumer/web technology. But there are (I think) a larger number of commenters who come from an engineering background, not necessarily computer/software engineering. So for example, when Slashdot posts articles on nuclear power, or aircraft, or chemical engineering, the comments section will often have at least a handful of very good comments from people in the field.
