RSS2PDF is a web based utility that allows you to take any feed (RSS, OPML, Atom) and output it into a PDF format for your archives. This is really cool and I can see this type of application being useful for a lot more that just archiving blogs and such as now they have added a Flickr 2 PDF conversion as well.
If you think that is cool check out their unofficial section where you can PDFize the last week of Dilbert comics and more. Pretty cool!
