I wrote last month on how XML is useful for keeping track of the blogs you read. Now here’s a post that has a video showing just how easy it is to grab somebody’s RSS feed; it’s called RSS (and why you should use it).
(By the way, is it RSS or is it XML? The answer is that XML is really a generalized way of formatting data. RSS is done in XML. So they’re not the same thing at all, but when referring to blogs, they have become synonymous. Clear as mud? Good…)
