Twitter has a new look today, now more Facebook-alike interface.

Tweets are now on the right side, while your name, number of tweets, followers and following, who to follow, and trending topics are on the left side.
The tabs before are now on the top of the page that follows you as you scroll down. (Home, @Connect, #Discover, Search, Profile Settings, New Tweet)

Now we can control and navigate Twitter with its Keyboard Shortcut functions.

Twitter Profile now looks more cool. Profile details are now in skyscraper mode.

On the left, there are tabs for your profile (Tweets, Followers, Favorites, Lists, Recent images)

What's your opinion?

Update: As I searched, it was rolled out last December, but some are still in old interface I don't know what is the true reason, the sure thing is, the new Twitter is coming.
