What Are Those Funny Little Subscribe Boxes Everywhere
You will have probably noticed that many of my pages have one or more graphics looking like:
This is a connection to my site's RSS feed. Yahoo! has an excellent introduction to RSS, but, in short, RSS is a mechanism for getting updates from a website that you are interested. The website publishes a feed. You subscribe to the feed via a program called an aggregator (AKA: reader or viewer). The job of the aggregator is to take the entries from your feeds and show you what is new. The best summary is that RSS plus an aggregator basically lets you build your own customized website.
If you haven't started using RSS, I strongly recommend it. Starting with an online aggregator is probably best. If you are a Yahoo! fan then My Yahoo! is probably not a bad choice (help page), and if not, I recommend the Google Reader.
