Twitter has launched its official iPad app . There's a bit more to this than the standard mobile Twitter app. "Twitter for iPad takes advantage of the iPad's fluid touch interface, letting you move lots of information around smoothly and quickly without needing to open and close windows or click buttons," says Twitter's Leland Rechis. When you tap a tweet in this app, it opens a pane, and depending on the content of that tweet, you can open videos, photos, articles, etc.
