Japanese video website overwhelmed by otaku in which comments scroll over the video at the place in the video where they were typed. For instance, if a comment is typed while the watcher is at 2:00, then all users from there on will see the comment fly by at 2:00, everytime. Sucks because you have to sign up to watch videos, and is impossible to navigate if you're an English speaker like everyone else. Available in every language but English, such as Supaanishu (Spanish), Garman (German), and amazingly understandable Taiwanese. This site is only good for MADs (which are AMVs, but actually decent), and Vocaloid.
