Nice work. I'm waiting for the next versions. The alpha is so promising!! The animations are really smooth.
During my tests, I've seen that flash videos weren't displayed. Some things also annoying me: content is displayed with the website design even if I'm still in the app (meaning I've not click on the browser icon), the back icon doesn't have the right icon and content is loaded in a too lazy manner. If you don't use it, consider looking inspiration in Reeder App for iPad (a must have).
I hope my remarks will help you. See you.
