The problem with apps is that they don't have tabs. I can only view one thing at a time, and the way I use Reddit (open a bunch of links in new tabs to read one at a time, or to refer to two things at a time) doesn't work without tabs.

It's the same with the Amazon app. The website is atrocious because pressing back after viewing anything shoots you back to the top of the page, but the app only lets you see one thing at a time.
