Whoo Hoo! Did you take a look at your site meter and see if it got you any extra traffic?

Cool, Matt; right on!

Cool Mat, that's very encouraging and gives one the feeling of doing something worthwhile. I had the same feeling when I discovered that my web site or parts of it have been cited as reference material on other web sites and/or forums.
Good on you keep going.
