I'm almost exclusively a lurker. I don't visit meetups and don't read the Rationality Quotes threads. What I largely use lesswrong for now is the aggregation feature of the "RECENT ON RATIONALITY BLOGS" tab. I suspect I could duplicate this functionality with some combination of RSS Feed/blog subscription feature, but I'm unmotivated to do so and have convinced myself that the blogroll list curated by LessWrong is valuable. Hopefully my experience is demographically representative enough of a larger pool of lurkers as to be valuable.
My only two comments are one I made on that post inviting lurkers to post and this one, but I did take last years survey for what it's worth. Though I don't recall my answers to last year's survey, I suspect they line up pretty well with this year's. I wonder if there's any potential in the data to track how respondents answers change over time.
I have taken the survey.
