Oh yeah... that *is* better.
Who needs an HTML parsing linkback extractor, just grab the refering site's RSS feed and XML parse out the goodies. Very cool! Why didn't I think of that! Sam Ruby explains how to do it. What about sites that don't have an RSS feed and don't indicate it's presence via a link tag? They don't deserve a linkback!
Update: I was kidding, of course. Some of my favorite blogs do not have RSS Autodisovery. I agree with Bruce's earlier post, a linkback implementation should use a combination of HTML extraction and RSS parsing to get the refering post's permalink and excerpt.
