While people in the US move to FriendFeed or Plurk, Japanese move to Wassr.

Wassr is one of the most popular twitter clone service in Japan. It has stared service about year ago, now has almost all the same features of Twitter(like API, mobile version site...).

First I noticed some Dowango(runs NicoNico Douga) ppl go to wassr a couple of months ago while twitter is down. And now more and more ppl move to Wassr. Most of the people do multiple post to Twitter and Wassr, though.
