The current interface is fairly difficult to use on a mobile device. (where i usually watch reddit.tv)
Would it be possible for a more mobile friendly version of the site?
Well the SPEED of the interface isn't the problem. It's accessibility.
Personally, I'm working with an android 4" screen @ 480x800. I usually use Dolphin HD.
I have no problem watching the videos themselves mostly, it's the act of moving from video to video and selecting categories that gets cumbersome.
