I came across this video on the Blue Flavor blog.
It’s a great, high level, introduction to what RSS (Really Simple Syndication) is.
[Update 9/4/2010: Unfortunately they made this video private on YouTube.]
“There are two types of Internet users, those that use RSS and those that don’t. This video is for the people who could save time using RSS, but don’t know where to start.” – leelefever at the Common Craft Blog
Definitely worth a watch. -k
