Facebook: The End of Class Reunions?

Chances are if you graduated from high school at any time of the 90's, you are now on Facebook, connecting with all your teenage angst again. Could the advancement of Facebook also result in the demise of the high school reunion? Is there a need to see your high school facebook friends in one place after 20 years?  Will high school reunions simply become a dreary coffee date for the people of your graduation class who *aren't* on facebook?

Wow. There are only about 4 people from high school who I still am waiting to join facebook. Hurry, or I've got to go to the reunion!
