I'm in the top 1.5%, even though I hardly have written anything here, and the comments are full of similar anecdotes. I guess there's a _ton_ of people lurking, and the active community is actually quite small. I find that quite surprising.

I am at 0.77% with only 73k words. And the top commenter is at 4 million. Is this website counting people with 0 words too?

Long tail. I wouldn't call them lurking they do what satisfies their itch.
