Very nice, thanks. One thing that is odd/slightly annoying is the way the comments initially scroll up. The issue is that the comments list scrolls at a different speed to the speed at which I'm dragging it due to the simultaneous scrolling up of the title bar. I think initially just the title bar should slide out of the way, and when it's gone, scrolling should continue on the comments list. Ultimately my finger should at the same position in then comments list as when it started the drag. i.e. Very much like how a category slides out of the way in a regular UITableView.
Actually this affects the main news items list also.
In addition, when I'm part way down the list I can't tell whether the grey "x Points ... y seconds ago by zzz" separator bar applies to the item above or below it. Maybe adjusting the shading of the bar and border would make it more obvious to which it belonged.
