I found this an interesting second view into someone's participation on a Stack Exchange site. And, y'know, what's the point of earning badges if not to show them off?
The old Users page showed them, but the new reputation-league-style one doesn't. The new display of top tags for the current time period is also great information at that level, and I know there's a balance against presenting an overwhelming amount of detail in a small space. Still, I hope a solution to include both could be found.
EDIT: not just to show off. When I go to the users page, what I generally want is an idea of who the notable users on that site are (see Aarobot's comment here). That may or may not correspond to who's been active/helpful recently, which is what the new page seems geared at showing. And that's why I miss badges.
