Twitter co-founder Biz Stone thinks a picture can be more meaningful than 140 characters of text.
That's the concept behind a smartphone application released Tuesday by Jelly Industries. Stone launched the San Francisco startup nine months ago without revealing what he was working on.
Jelly's free app for Apple Inc.'s iPhone and phones running Google's Android allows people to tap into the collective knowledge within their networks on Twitter's short-messaging service and Facebook's online hangout to find answers about things that puzzle them. The questions are accompanied with a photo of the object that triggered the curiosity.
Stone played an instrumental role in building Twitter Inc. into one of the Internet's most valuable companies. His exit from Twitter nearly two years ago raised a great deal of intrigue about what his next act would be.
