Today I received access to try out the new Twitter.com web application. I call it that because this is by far the best desktop experience I have had with any Twitter app. The information you want is displayed conveniently next to your timeline and images from yFrog and Twitpic are loaded right into the Twitter website.
The app is filled with keyboard shortcuts that make navigating a breeze and with the panel on the right following a conversation is now much easier. The new version is also faster, switching from the main timeline to your mentions and back can now be done in the same second. The new Twitter web site also features useful information from your profile at the top of the right panel on the homepage.
