Web 2.0: changing who contributes to Web

Today I received a Netlingo 'Word of the Day' email with some interesting data on how Web 2.0 technology is changing who contributes content to the World Wide Web:

1% rule

An emerging rule of thumb that suggests that if you get a group of 100 people online, then one will create content, ten will interact with it (commenting or offering improvements) and the other 89 will just view it (also known as lurking). Earlier metrics garnered from online community sites suggested that about 80% of content was produced by 20% of the users, but the growing data due to social networking sites and blogs creates a different picture. The lesson? A Web site that demands too much interaction and content generation from users will see nine out of ten people just pass by. (http://www.netlingo.com/)

If this is the case, then there are a lot of people out there who can contribute to our library's Web 2.0 'face'.
