Thing 1 was create and register a blog.
I already have this blog, so I registered it for the program. You can find my blog and a list of other blogs in the SAMMIE region listed here: http://23mobilethingsmn.org/sammie/.
If you do not have a blog already set up, Tumblr and Blogger were recommended. Here are some brief thoughts of Tumblr, Blogger, & WordPress:
Tumblr – If you are Youth Services/Teen Librarian, this is the blogging site for you as it is used more by younger people. The usability is also not that bad.
Blogger – Blogger is a good beginners blogging site. I say this because the ease of use if fairly simplistic.
WordPress – While the usability on this site can often be difficult and frustrating, it allows to have a more professional, almost website-like blog.
