Why Twitter outguns Facebook in Japan

Interesting observation (although technically they mean pseudonymity, not anonymity):

"The one thing all the popular Japanese social media platforms have in common is anonymity. Whilst Facebook is all about the people behind the profile, the Japanese web population typically like their privacy, with nicknames, pseudonyms and other monikers used to disguise their true identity."

Makes sense to me. Mixi is a localized incumbent that supports anonymous profiles. Facebook relied on crowdsourced translations to make the Japanese site (which I think is an amazing idea), but that's not going to cut it as far as localization goes. For very similar reasons, Yahoo! was able to control search in Japan when Google took over much of the rest of the world.
