Stephen Downes outlines How to Create an RSS Feed With Notepad, a Web Server, and a Beer, essentially a 9 step process for (ugh) writing RSS Feeds by hand.
An excellent one paragraph summary of what RSS is, indeed, but I would hardly recommend wiriting XML in a text editor unless it is for the command line groupie club. XML code is really best for machines to digest, not humans (or canines).
Stephen’s point might be that RSS is simple enough, and maybe one beer’s worth of effort is not much to ask for.
However, it is this dog’s opinion, that our suggestion for Writing RSS 1-2-3 is much easier as it is via a web form interface, it composes all the grunt XML code, and better yet, once your RSS file is stored on a web site, the tool we recommended can suck the current content back into that form.
We think it is more like a shot of fine cognac than gulping a bottle of warm Schlitz ;-)
Regardless, everywhere I look I see much more opportunity for RSS feeds than implementations.
