Seems like the landing page is full of fluff. All I see are feel good sentences about helping each other, Albert Einstein, etc.

The big down side is this: "“What’s this?” That query is submitted to some people in your network who also have Jelly".

I have +400 friends on Facebook. Out of those, maybe 3 will install Jelly to try it out. Even with taking friends-of-friends taken in to consideration, it's just a very limited set of people. Would I really want to use this app to post a question that I can probably find answer just by looking a map, doing a google search or posting to Facebook/Twitter?
