I like this app and don't mind whether it's new posts at the top or the bottom.
What I would like to see is whether there are any comments on friends' status updates (and how many).
Also, not sure if it's been reported elsewhere, but I couldn't leave any comments myself - got an unreadable error message (yellow bar with white writing, overlaid on the white writing on the screen making it impossible to read).
Keep it up though, every new app is a godsend!
