1-9-90 rule

Het is al wel een tijdje bekend, maar ik had er nog nooit van gehoord... Dus ter eigen informatie;

•90% of users are "lurkers" (i.e. they read or browse but don't contribute)
•9% of users contribute from time to time, but other priorities dominate their time
•1% of users participate very often and account for most of the contributions

But you got to love the lurkers, want daar zijn je wins te halen...
