"These writers, despite the famed interconnectedness of the web, seem uncommonly starved for connection."
The currency of blogging is links. I link to you, you link to me, we comment on each other's writing. It's constant interaction, perpetual peer review. Books cannot link (in the same sense). The reason that blog posts collected in a book seem "starved for connection" is that the material was never meant to go in a book. When you take something out of the environment it was made for, depends on, and made IN, of course it seems incomplete.
Final pet peeve about this review: the pretentious use of "Y'all" to detract from the form of writing. Ugh.
