How would you be affected if all of your personal data on the internet was completely wiped?

Let’s just imagine by some freak accident that all of your personal data has been wiped off the face of the internet and none of it was backed up. Your identity on the internet, just gone. POOF!

By “personal data”, I’m talking about all your photos, videos, blog entries, tweets, website accounts (God forbid your Fluther account, including all your lurve, questions, and answers), and anything else you have posted or uploaded to the World Wide Web.

What would your reaction be? How would it change your life until you recover from this disaster? How much personal information would you have lost (a lot, not much)? How long do you think it would take to recover? Do you know anyone who would practically not be able to function if they lost their data? Any other thoughts about this happening to you?
