We bet you've been sitting there, sipping your morning coffee and thinking to yourself, "you know, it's been a while since Facebook added some big names to its roster." Fret not though, the social giant is bringing the talented folks from the design firm Teehan+Lax into the fold. If the name doesn't ring a bell, don't worry. This is the company that helped put together the deliciously spartan looks of publishing service Medium, Readability and gave Canada's Globe and Mail a much needed face lift. The most immediate and obvious use of the new talent would be to bring a visual refresh to the Facebook homepage. But the minds at Teehan+Lax could also bring a much-needed breath of fresh air to the social network's mobile apps.
