I tend to forget things. Ok, things I read, I get it. When I find myself having to refer back to lectures I gave, or, heaven forfend, papers and chapters I've written, I realize I've got a problem.
This site is meant, really, only for me, to provide a running record of stuff I knew a lot about at one time, perhaps a cool article that I really liked, or maybe the outlines of a lecture I would love to present in the future. But, in the end, it's just sort of my intellectual "Dear Diary."
