user participation - Internet Marketing News and Blogs

Speaking at the Web 2.0 Expo industry conference in San Francisco this week, Bill Tancer of Hitwise revealed that Web 2.0 sites have lower levels of audience participation than is commonly assumed.

For instance, a mere 0.16% of visits to YouTube are by users who are actually uploading material, with the vast majority being visits by 'lurkers' - people who do not contribute to the site.
