I found this out as I was going to their site to sign-up for an account - which now I can't do. Does anyone know of some alternatives they would recommend?
You should check out my up and coming startup, http://AppRabbit.com. It's still in beta, but it's coming along nicely and may provide the functionality that you're looking for. Shoot me a note if you have any questions or to chat about what you're needing to build; megamark16/gmail.
Reminds me a lot of Freebase Gridworks (http://vimeo.com/10081183), but I'm not too familiar with either product so that may be a misperception on my part.
