Infogr.am, Watchlater and Cobook have amazing consumer traction and will definitely be great exits for HackFwd in a couple of years. Some other companies like Yieldkit or my own Filmaster.TV have pivoted towards a b2b model and generate proper revenue in their niche (we help cinema exhibitors and television providers learn about their customers tastes, personalize marketing communication and grow their audience). Others like Visualnest and BeamApp are fascinating pieces of technology still looking for the right application. I believe only FlockOfBirds has officially closed down.

If you have specific questions about any of the startups, let me know, I'll be happy to help.
