Facebook is planning a major site design and is showing off some minor tweaks that are an attempt to de-clutter the increasingly cluttered FB experience. They are playing around with tabs – one for the about page, another for photos and of course, the Wall. “We’re trying to make profiles more simple and relevant, while still giving you control over your profile and how you express yourself,” Facebook’s Carolyn Abram writes on FB blog. Some of these design changes will be rolled out to FB users over next few weeks.
