I like browsing HN from the Android app Materialistic because (1) I can't see votes on my posts and (2) it's difficult to find replies to my posts (you can view your profile, but jumping to a post only shows its ancestors, not replies). This combination, plus the annoyance of typing on a smartphone, means I usually * only comment when I have something that adds value to the conversation; I tend to engage more with the content and less "socially".

* Of course, there are exceptions, and I actually use hnreplies.com to get emails when someone replies to me, but there's enough of a delay that I usually am able to avoid getting caught up in a back-and-forth argument. Especially since, by the time I see the replies, someone else has already clarified my position :)
