I think this is a nice concept. I dont blog but I've been considering starting one for a while and this design concept might be enough of a gimmick for me give it a try. What I can't help but see is that if you strip away the design its really just another blogging platform. Depending on how much time/money/resources youre willing to throw at it, I think it would make for a nice art project. If were you and also had access to free bandwidth I'd trial it.
