I visited Facebook's Statistics section today and came across these figures:

• Average user has 130 friends on the site
• Average user sends 8 friend requests per month
• Average user spends more than 55 minutes per day on Facebook
• Average user clicks the Like button on 9 pieces of content each month
• Average user writes 25 comments on Facebook content each month
• Average user becomes a fan of 4 Pages each month
• Average user is invited to 3 events per month
• Average user is a member of 13 groups

This is fine and dandy, but I'd like to see another deeper subset of metrics:

• Average time spent on Fan pages
• Average time spent lingering on individual photo albums
• Average time spent looking at the main section of the news reader
• Average time spent creating and editing friend lists
• Average time spent removing one's self from Groups and Fan Pages
• Average time spent attempting to upload a video or phot
• Average time spent checking new comments/likes to status messages (including a lumped up summary from mobile AND web)
• Average time spent updating status message with the 'tagging' feature of another Facebook user

Anything else you'd like to see added to Facebook's public set of metrics?
