POPFile is happily catagorizing my emails and discarding all my spam. Catagorization is very useful! I’ve also been catagorizing the webpages I run across that I want to come back to later. I had been using good old fashioned bookmark&tm; technology, but when I started throwing everything into the same bucket, it devolved into a gigantic list of links that was less than useful. So now I’m using the research, note taking, fancy pants tool CatClip to do the work for me. Even if I didn’t know some of them personally, I’d still say the developers of this tool have hit upon a good thing.
