Twitter tests out another desktop redesign with trends on the right, navigation on the left

It was in January that Twitter announced that it would be rolling out a new, simplified desktop redesign to its users. Six months later, we can confirm that Twitter is... still rolling out tests as it tinkers with a new look for its Twitter.com desktop interface. In the latest version -- which appeared to get teased earlier in the year but now appears to be getting rolled out to a wider number of people (see here, here, here, a tipster who sent us screenshots from Canada, and many others) -- Twitter's desktop appears as three columns, with trends shifted to the right column, and all of the menu and navigation items (plus a link to your profile) that had been at the top now listed on the left.
