Web 2.0 - Online communities map

I came across a very weird map on an even weirder blog about strange maps.

"Somewhat in the style of a treasure map, this ‘Map of Online Communities’ shows MySpace, Wikipedia, SecondLife and other user-generated phenomena now populating the internet.

The geography is not as random as one could assume at first glance. Area and position are significant. Thus, each community’s geographic area represents its estimated size, and the ‘compass-shaped island’ gives clues as to what each quarter signifies:

> North are more ‘practical’ communities
> South is for the ‘intellectuals’
> West lie the communities with a ‘real life’ connection
> East those with a focus on the web itself"

The map was originally posted/created here. They sell it as a poster for 12.99$.
