Jelly tries to get answers to the questions that keep you awake at night. A question we've had since its launch, however, was why it lacked any kind of comment or thread system. Fortunately, that's Jelly's new feature. Once you've got an answer, but you'd really like to hear some more detail, you (or whoever answered) can continue the dialogue below. These replies are also public, so they could help everyone. Biz Stone's new project just got a lot more viable -- provided you can find someone to answer your question in the first place.
