Highlight Highlight is another iPhone app that's trying to connect you with strangers based on mutual interests and friends in common via Facebook. The app does all the heavy lifting by running in the background of your iPhone and alerting you when someone of interest is nearby. It then brings up the profile of the user with information that's pulled from Facebook and allows users to message each other. Two main downsides to the app: Since Highlight only launched a few weeks ago, there aren't enough people on it for it to be useful. It's also a major battery drainer. -- Written by Olivia Oran in New York. >To follow the writer on Twitter, go to http://twitter.com/Ozoran. >To submit a news tip, send an email to: firstname.lastname@example.org.
