RSS for Blogger users
RSS is a highly formalized output format for regularly updated information (like blogs). If you've ever used an RSS reader, then you know that RSS is a Good Thing (thanks to RSS, I read many, many more blogs than I could otherwise--but if a blog lacks an RSS feed, I probably read it rarely or not at all). Many blogging tools can generate RSS automatically, but Blogger isn't one of them. Blogger Pro generates RSS (though with spotty results, apparently).
RSSify by Voidstar to the rescue. This acts as a "scraper" for Blogger blogs. If you want to provide an RSS version of your blog, you'll need to add a couple special tags to your Blogger template to help it parse your blog's contents. You can then provide a link to your RSS feed on your blog.
Voidstar also has a pretty complete-looking RSS FAQ.
