Kevin Werbach points out that two of the top five sites on Alexa’s Top 500 are in South Korea.

While Korea may lead the US in broadband and cell phone Internet access, I find it hard to believe that two South Korean portals are more popular than Google.

Could it be that Koreans are more likely to install and use Alexa’s software? I would take any data from Alexa with a grain of salt.

It’s nonetheless amazing how much of the Web may now be simply invisible to English-speakers.
