> RSS starts with an original Web site that has content available.
Not really true. You can offer an RSS feed without a website. I do. You do not need a website to create an RSS feed; any text editor will do, or any decent database will output RSS (I use FileMaker Pro). You could probably use Excel to output an RSS feed for that matter.
> While HTML is designed to present information directly to users, RSS is an automation mechanism for computers to communicate with one another.
That is also a questionable statement. RSS provides information directly to users through the newsreader or aggregator. You are reading essentially the same information through a different application than a web browser; however, you can combine the reader and the browser like Google Reader does.
The key issue is -- why aren't more folks using RSS and more government information sources outputting one or more RSS feeds!
