When I click on "more comments" in a question (for example at this question), the comment field gets the focus. Which is annoying on the iPad because the keyboard gets visible and takes up half the screen. It would be great if no text input area / field has the focus as we then would be able to view the comments (as requested by clicking on the 'add / see more comments). I know that this is also the button for adding comments, but the behavior slightly annoys me when I only want to read the remaining comments.
Well, doncherry is right:
I think the answer to this one will be: The site is optimized for normal screens, on which this problem isn't a problem; for mobile devices, there's the mobile version. The iPad and other tablets are something in between, unfortunately.
A lot of the issues that the iPad interface has to deal with -- weird skipping, screen real estate issues, etc -- are usually covered by switching to the mobile view. Of course, having actually used an iPad to surf the site, I can say that I really dislike the chat interface in mobile. So, I sympathize but unfortunately, switching to mobile is the better option, even if a good amount of the functionality changes in the switch. It's up to you to make the call; screen real estate vs. function.
