Yahoo's Bradley Horowitz applies the 1% rule to Yahoo Groups:
"1% of the user population might start a group; 10% of the user population might participate actively, and actually author content, whether starting a thread or responding to a thread-in-progress; 100% of the user population benefits from the activities of the above groups."All 100% benefit, but the work of the community is done by a very few at the top, and a small circle around them to offer encouragement and motivation.
How it works elsewhere:
- 50% of all Wikipedia article edits are done by 0.7% of users, and more than 70% of all articles have been written by just 1.8% of all users.
- On YouTube each day there are 100 million downloads and 65,000 uploads - or 1,538 downloads per upload.
The conclusion, and lesson for would-be web-entrepreneurs? "Certainly, to echo Field of Dreams, if you build it, they will come. The trouble, as in real life, is finding the builders."
