Why is it that every single social network community site makes you:

• re-enter all your personal profile info (name, email, birthday, URL etc.)?
• re-add all your friends?

In addition, why do you have to:

• re-turn off notifications?
• re-specify privacy preferences?
• re-block negative people?

AKA "social network fatigue problem" and "social network update/maintenance problem".

I love the mockup.
