Web apps! They're more and more like real apps. Take the new Twitter.com. It's pretty damned amazing. Is it so good you can ditch desktop Twitter apps forever?
The new Twitter feels a lot like an application, slapped on top of Twitter.com. That's partly because it's built like an application. It uses the same Twitter API that any third-party app does. The two-pane split view recalls the iPad Twitter app, and the design intent is largely the same: to keep you on Twitter.com while you're consuming the content the people you follow are tweeting. The right pane is like an activity panel. It expands out to show conversations between users, photos, videos, profile info, location and more. And the whole thing flows insanely smoothly and dynamically, like an app. There's infinite scrolling, so tweets keep coming as you scroll down. When you click the arrow to expand a tweet into the right panel, it shoots out like a card. There's even keyboard shortcuts and autocomplete like a real app (or Gmail, another exemplary web app).
