As somebody who is about to start grad school, blogging about papers publicly sounds like an excellent idea. At the beginning of my Master's degree, I was quite careful about making notes about every paper I read, but as I gained more background and started focussing on doing on my own work, I'd read papers only enough to get what I needed out of them (fortunately I have a good enough memory that when I needed something I'd already read about, I could often find the paper -- and I was religious about at least saving all the papers I read). Doing it publicly might keep the motivation up.
