1% rule

The term was coined by authors and bloggers Ben McConnell and Jackie Huba,[2] although earlier references to the same concept[3] did not use this name.

The paper concluded that the 1% rule was consistent across the four support groups, with a handful of "Superusers" generating the vast majority of content.

This latter distribution is still unknown and likely to shift, but various researchers and pundits have speculated on how to characterize the sum total of participation.

[10] A similar concept was introduced by Will Hill of AT&T Laboratories[11] and later cited by Jakob Nielsen; this was the earliest known reference to the term "participation inequality" in an online context.

[12] The term regained public attention in 2006 when it was used in a strictly quantitative context within a blog entry on the topic of marketing.
