I started using algorithmic passwords a year or two ago and it has been great. I have a different password for every domain, there is nothing to remember, and it is hard to crack. I just tested my password on this demo and got a four out of four score. I know others have done this but I don't know why it isn't discussed, or better yet, recommended more.
