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.
