It's not just indie stuff, there's a good mix of mainstream and some manga on the lists. There are even some art book suggestions.
Maybe you would like to share your Best of 2008?
One of the books I recommend that is on the list is Tekkonkinkreetby Matsumoto Taiyo. I read the Japanese version years ago. I don't know if the translated version is as good, but it's a weird and brilliant piece worth checking out.
