Georgi Kobilarov illustrated the difference that aggregated linked data should make in the lives of people. He said that on his smartphone, he can download apps from Qype and Yelp and Foursquare and any number of data providers about listings or venues, using geolocation to tailor the content to where he is. But he doesn't want to have to check a multitude of data sources to find out what to do. He doesn't care about the apps themselves, or the app provider, he cares about the information that will help him plan his evening. He wants an app that bridges them all, and uses information from Facebook and Twitter to say 'There is a pretty lousy bar around the corner, but two of your old high school friends are there, so it is probably your best bet right now'.
The news and journalism version: "Accident has happened in a remote location, you have friends currently on vacation there… send them a message on Facebook to see if they are ok?"
