What's Bubbling Up?

I've been playing around today with What's Bubbling Up.  It's a promotional site for Unicel, created by the brilliant minds at Kelliher Samets Volk.  The site focuses on the idea of making connections by allowing users to create and post messages.  I always enjoy sites based on user content, especially when they invite people to share something they might not normally.  I also really enjoy the thought of unspoken conversations being these lingering speech bubbles - it's a cool visual.  This site reminds me of one of my favorites, the Hope Garden.  (Thanks Jackie!)
