Great post over at RSS4Lib about placing Creative Commons licensing information into your RSS feed. This is a fantastic idea because the entire purpose of RSS is to let others have control over how they receive your content. This allows you to convey your wishes for how people can use what you create within the medium itself.
This reminded me to update the footer information for this blog (look at the bottom of the page if you are viewing this on the Libology web site)
