This is extended in the post/article "Most of What You Read on the Internet is Written by Insane People" [0].
> The 1% rule is of course just another way of saying that the distribution of contributions follows a Power Law Distribution, which means that the level of inequality gets more drastic as you look at smaller subsets of users.
> Wikipedia's most active 1,000 people — 0.003% of its users — contribute about two-thirds of the site's edits. Wikipedia is thus even more skewed than blogs, with a 99.8–0.2–0.003 rule.
> 167,113 of Amazons book reviews were contributed by just a few "top-100" reviewers; the most prolific reviewer had written 12,423 reviews. How anybody can write that many reviews — let alone read that many books — is beyond me.
> YouTube power-user Justin Y. had a top comment on pretty much every video you clicked on for like a year. He says he spends 1-3 hours per day commenting on YouTube, finds videos by looking at the statistics section of the site to see which are spiking in popularity, and comments on a lot of videos without watching them.
> If you consume any content on the Internet, you're mostly consuming content created by people who for some reason spend most of their time and energy creating content on the Internet. And those people clearly differ from the general population in important ways. I don't really know what to do with this observation except to note that it seems like it's worth keeping in mind when using the Internet.
Of course, that post's author is clearly insane. With 72k reputation and 1000 posts on Stack Exchange, I'm proudly insane. And if you're about to reply with a witty comment, you might just be insane, too. ;)
