Facebook Testing New Timeline Format

Mashable reports that Facebook is testing a new design for profile pages that places all posts in a single column on the left, while activity updates, friends, places, apps and other sections are on the right.

The current format, a two-column layout, includes posts on both sides, forcing users to look back and forth.

In its new incarnation, Timeline no longer has the vertical line that divides a profile in half.  Clickable dates that help users navigate through profiles, however, are still listed on the top right.
