Here is +Mashable's report on the upgraded Highlight (an app for iPhones that shows you other users who are within 100 yards). I used this as at the Flipboard Party last night. This continues to be one of my favorite new apps of the year. I'm not alone. Famous investor Ron Conway told me it's one of his too. If you look at my account there I've already Highlighted 2,700 people, many of whom are a "who's who" of the tech industry. 

Definitely makes Highlight more useful.

Why? It lets you add notes about each user. The UI got lots of tweaks. It seems like my battery is being used up less (although I really don't care, I have three Mophie packs now).
