I recently appeared on CNN to talk about apps that use location data embedded in Tweets and Facebook shares as well as other social media to present you with social media info in new ways, from showing you conversations that are happening in your immediate geographical area to what’s happening anywhere in the world you want to zoom in on. These people discovery apps can help you find people and make new friends and connections, but obviously there are some privacy issues around this that we need to discuss in greater detail. Curious? You can download the two apps I talk about, Highlight and Banjo to see for yourself and draw your own conclusions about what’s happening in the social space.
