Perhaps I'm in the minority here but I never go to facebook to find specific information, it's more of just a perusal of crap to waste time. In the regard I believe a grid would be an adequate design to move to as it's more apt to visually scanning items which is typically what I do now. The only caveat I can see is that items in a straight line lend the eye to snapping back to the original position. Not sure if a staggered setup would fix that issue or if slight archs would help.
