I'm reading Chris Anderson's FREE at the moment (in the seven seconds of free time I have) and he mentioned a very interesting theory on the ability of a community to be function. Also the ability of someone to maintain more than 150'ish relationships.

 Given my very public stance on my view of the insanity of auto-follow on Twitter and the fact that I culled my Facebook account down to under 150 people I actually know - this theory fascinated me.

 Here is the Link to the Wikipedia article on the subject - very interesting.

 btw - how INSANELY good is Wikipedia from Kirsten Dunsts height (don't ask) to Dunbars Number

 Here in the Dale household a day would not go by without consulting it.

 I do understand it's short comings - anything that is "opinion", political or controversial has to be read with two eyes WIDE open.

 For factual stuff - it's just insanely good.

 PS - It's also another great reason to have an iPhone - Wikipedia EVERYWHERE rocks!
