I'm kind of a lurker as well. I read HN comments to gain a broader perspective on issues. Sharing my own thoughts on the matter doesn't really help with that.

Of course, sometimes when reading comments I get the feeling that you people are all entirely, inexcusably wrong, and I feel an urge to set the record straight. Normally on HN, it doesn't take long for someone to step up and explain exactly what I was thinking with an eloquence I couldn't have matched. And the world is right again. :-)
