We're going to release new markup that Kevin has designed that is more mobile-friendly. (Sorry, I don't have an ETA, but we're working on it.) When it comes out, please let us know if this is still a problem.
Dang, since this is already a meta/feedback-y topic, I'd like to add another request: consider giving YC employees /HN mods a distinctly colored username, similar to how the OP is shown in green. I'll probably lose all my cool points to admit this, but I didn't realize who 'sama' was that posted this thread :)
