XKCD‘s 2007 map of “Online Communities” has been updated for 2010! This is a great example of making a set of dry stats entertaining. It’s essentially a map of the popularity (by various measures) of certain sites and technologies, but presented as a map (not entirely unlike something you might find in Lord of the Rings). Of course, in doing something like this you don’t get the size of each community down to the last decimal place but that doesn’t matter – the measurements are so open to interpretation anyway that presenting the actual numbers is meaningless – its the approximate relative sizes that are more interesting.
Here is the current map (scroll down for the 2007 version):
