What would you expect this map to look like? Do you expect to see many different websites? Or just a few? Do you expect the world to be mostly the same color? For countries near each other to have the same top website?
The data are from Alexa and the countries with “unknown” best I can tell do no produce enough data to be ranked. Google’s country domains (.ca, .jp, etc.) number 200+ and are all included as “Google.” No properties are included (flickr.yahoo.com for example).
Some things do pop out:
Russia and China like their websites homegrown. Russia’s Yandex is a search engine as is China’s Baidu.
Cameroon and Japan prefer Yahoo. Do those countries have anything else in common?
Why does Kazakhstan like to e-mail so much?
What other questions does this map raise?
