LOL! Most of the 20-somethings crowd makes "Facebook events" which are reminders on Facebook about real-life happenings - and for a lot of my volunteering and huge religious friends circle - this is how you get the word out about events and stuff.

I also seriously need reminders about birthdays because otherwise I'd likely forget most people's.

It is true about the social interaction thing... most people I talk to on there, I could easily see in my real life - and a lot of them I actually DO see on a regular basis... but it's easier to organize events and RSVPs on Facebook then by email...

I admit I spend most of the time on blogging quizzes/surveys and on pointless applications though.
