Thanks all for the comments - they're energising :P
Here something fun to share which I just stumbled over searching the web
http://imgs.xkcd.com/comics/online_communities.png
Somewhat in the style of a treasure map, this ‘Map of Online Communities’ shows MySpace, Wikipedia, SecondLife and other online communities.
The geography is not as random - 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.
Have fun,
John
