National UnFriend Day

Today is Jimmy Kimmel's National UnFriend Day, when you're supposed to clean out your Facebook friend list to eliminate the people you don't really consider friends.

Am I participating? No.

Sure, there are people on my Facebook friend list with whom I haven't communicated in years. That includes digital communication.

I have nearly 500 Facebook friends, and I'm ashamed to admit that I still sometimes ask "who is that?" when I see some of them on my news feed.

Still, "unfriending" seems so harsh. And let's face it, more Facebook friends means more potential for Facebook stalking. Which I love.

What's your criteria for ending a friendship on Facebook?
