Hey, Eleanor. I'm pretty sure all of the blogs listed in this team are outside blogs (blogspot, wordpress, etc.) Some of them are directly related to or are about their Etsy products, but they are not hosted through Etsy.
If you want to get started, here are a couple of links to blogging sites:
http://www.blogger.comhttp://wordpress.com/If you want to learn more about blogging, I would suggest just clicking through the blogs listed in this team. There are some very good ones, and they can give you some general ideas on how a blog should be set up, or what kind of things to write about. Otherwise, it's pretty much up to you what you want to do with it.
