Effectiveness breached

I'm by no means Magellan here, but I need to say that my facebook circle has become unmanageable. Here's what I'm talking about:


Forty-six updates during an afternoon nap. That's just too many.

It makes me think of a concept I read about a few years ago called the "Dunbar number." It's the maximum size a group can be before it becomes ineffective. It's generally said to be about 150, which means I'd have to pare my friends by about half.

For whatever it's worth, I only have one facebook friend actually named Dunbar.
