I've seen some videos on Niconico with English comments but those were a lot harder to read. Perhaps concepts-per-second between EN/JP are similar if reading a static page, but English text tends to use more characters than JP text that express the same idea, making the system scroll it faster and thus harder to read as they whiz by. Maybe it's a Niconico issue and the system is tuned to reward comments in the typical JP length to be the most readable; I'm not sure.
