This and voting up/down are a pain on the mobile UI. It's too easy to downvote instead of upvote, or flag something without even noticing in this case. (I just found two perfectly normal posts I've flagged)

I think the main reason is the Web1.0 design of HN doesn't translate well to small screens.

Yes, I have 30% failure rate in mobile, even when pinching. I always now check for "undown" or "unvote".

Fwiw, there are some pretty great HN reader apps I’ve found — Hack and Octal are the two favorites I’ve come across for iOS.
