How Much Time Does Web 2.0 Take?

A post on the Museum 2.0 website provides readers with a look at the time it takes for people to engage in Web 2.0 activities.  While the blog itself is targeted towards the museum crowd, the data is still applicable for those in the information environment.  Here are the definitions posed by the author:

• Participants spend roughly 1-5 hours in the Web 2.0 world.  These individuals don't need a large amount of time or technical expertise to participate. 
  
• Content providers spend about 5-10 hours per week.  Some of this group's activities include writing blogs and creating podcasts.
• Community directors spend 10-20 hours per week.  This group has more time and technical expertise and are willing to take on bigger projects like developing community websites or creating a presence in Second Life for their organizations. 

What group do you fall into?
