To hear about it whenever I post, you need an RSS reader. I use Sage. Go there and download it, and voila.
I keep the Sage window open on my browser so when I am reading a blog I like, I can subscribe very easily.
Oh, and Sage only works if you are using Firefox. Firefox is better than IE (internet explorer) because it is community built- so any problems with it, and the ways it could be better, get talked about by programmers way smarter than you or me. And you get a product that is very good.
IE and Firefox both recently released new versions- Internet Explorer 7 and Firefox 2.0. Before you go downloading either, note that Microsoft always puts out bad products, and then partially fixes them over months and years (oh no, I am not biased at all!) and that Firefox 2.0 is a release candidate, so if you want something that works for sure, get the current firefox version that is for release to the public, version 126.96.36.199.
