I've always loved Port but never delved in to the understanding of how things work around it. I knew that, just like any good beverage, it probably had it's own designations, shelf life, vintages, etc., but that was good enough for me. More Graham's Six Grapes please.
Sommelier Courtney Cochran dropped me a note informing me of an article that the San Francisco Chronicle ran that covered Port in general as well as some nice specifics. Definitely worth checking out.
Also of note is Courtney's blog which is one of the few out there that is well thought out and doesn't try to take itself as seriously as some of the others. (ie her experiment in trying to get Thunderbird Wine to taste good).
