It was about a year ago when Google acquired, Slide; the company you probably know, because of the app it developed, Disco...Google's super-secret underground group messaging app. But it's about time, Slide bore some real fruits. Enter: Photovine; a smartphone app that lets users share a picture and add a tag to it and then watch other Photovine users add their pictures to the same tag. The app will be out in about a month.
