Eric Fischer, who previously brought us maps illuminating just how racially segregated cities in the US really are, has created maps of Twitter and Flickr usage around the globe, beautifully displaying the geotagged usage almost like star charts. The red dots are geotagged Flickr posts, the blue dots are geotagged Tweets, and the white dots are items that were posted by both internet services. Let's take a look at some choice samples from the Flickr photo set "See something or say something":

twitter and flickr usage of the big bend area of far west texas
Here is the region of the country I live in . . . if you look at the center of this image, you'll see four white star clusters, surrounded by red clusters; those white clusters are Marfa, Alpine and Marathon, with Fort Davis to the north. A lot of red dots surround them, plus a white cluster down in Terlingua, and a huge swath of reds representing Big Bend National Park. El Paso can be seen in the top left, and Odessa/Midland near the top right, with the white lines connecting everything being highways. In this region of the world, there is pretty much only cell phone coverage along the highways and the towns that the highways go through. The rest is open country, for the most part.
Now let's check out my home town of Boston:

boston is brightly lit with twitter/flickr activity
As expected, very very bright. Boston's a bit of a distant memory for me, but I'll tell you, it is so damned internetty there. Probably has something to do with the sheer amount of college students living there at any given time (250,000 in Boston and Cambridge alone).
Let's take a look at the entire planet:

this image makes me feel uneasy for some reason
Oh, uh, hmmmm. What does this remind me of. Hmmm. Perhaps this is an image of a younger version of this:

a borged up earth
What starts with Twitter and Flickr might end inevitably with the Borg. It would be interesting if Fischer would put these maps out annually, so we could watch the quick assimilation of the entire planet.
We are the Borg. We will add your biological and technological distinctiveness to our own. Your culture will adapt to service us. Resistance is futile.
