Fair enough... if that's coming from a small number of highly-ranked comments, that is indeed evidence that a lot of people are interested in the exchange. (If it's a large number of low-ranked comments, it's equally consistent with a small number of people who endorse your engagement in it.)

That seems like an accurate assessment. At present this comment http://lesswrong.com/lw/54u/bayesian_epistemology_vs_popper/3uqx is at +8 and this comment http://lesswrong.com/lw/54u/bayesian_epistemology_vs_popper/3usd is at +13 but the second comment also got linked to in a separate thread. No other comment of mine in that discussion has upvoted to more than 5. That data combined with your remark above suggests that your initial remark was correct.
