Visual Bookshelf 2.0 has been released, and I'm liking the upgrades. Given that it has to fit within the facebook column structure, the design works really well. The images also look better, although they're still smaller than I want them to be.
Hey, VB team - keep up the good work on facebook, but if you have some spare time to work out a full-page design that you can host on your own pages, I think you might get some usage there as well, and more space to do things like advertise.
Just a thought. :)
