1. "Since the entire feature is your Profile, it was confusing for the freeform user page in Profile to also be called Profile. For clarity, it is now called About instead. The functionality remains the same." So functionality should stay the same

3. I'm guessing they won't be available anymore, just your existing avatar and the new default ones

4. Since functionality is likely staying the same (see 1) others will probably still be able to edit your user page

6. User talk pages will remain an option, "Communities will still have the option to use User Talk Pages instead of Message Wall, should the admins decide to go that route."
