Mashable’s Ben Parr likes the new Facebook Timeline profiles, which are a radical change from the current profiles on Facebook:
The new Timeline interface is beautiful and a major time sink. However, this is clearly not a finished product. The social network must do more to clean up actions on the Timeline and avoid the “getting married twice” problem.
Overall though, Facebook has made profiles more personal. Users are going to be spending hours in their friends’ Timelines.
