The 1% Rule

Posted in Guardian (cross-linked through Emergic) :

'It's an emerging rule of thumb that suggests that if you get a group of 100 people online then one will create content, 10 will "interact" with it (commenting or offering improvements) and the other 89 will just view it.'

In our case:

For every god-knows-how-many people who are online, 3 'provide' content and 3 people 'interact' and 3 people 'view' it.
