Very nice. A few suggestions in case you intend to develop this further:

- The "Y" button for hiding/showing the list is maybe a bit too subtle. I only found it by randomly mashing everything on the screen on the theory that surely the functionality had to be somewhere. I think the problem is that it doesn't look at all like an active UI element.

- Going directly to comments doesn't seem to be possible. I guess you can just tap the list item and then show comments really quickly, but I would have expected tapping the comment count to do that.

- Would be nice to see which stories / comment pages I've already viewed.

- Would be even more awesome to see in the main list how many new comments were added since I last viewed the comment page of a story. - Is it really not possible to view more than the top 50 items?
