One of my new favorite Pinterest tools is the Button and Widget Builder. Available (located) with the Pinterest for Business resources, I have found it useful for promoting specific IRC Pinterest boards on the IRC News Blog (see IRC Pinterest Book Trailers, National Poetry Month, and New Ellison Dies); with one click, users access the full board from the blog.
I began pinning infographics, blog posts, and other items of interest about Pinterest on my ACRL 2013 Resources board for my workshop and have continued the practice on my Pinterest News & Info board. Here are examples of the embedded boards.
Update: Well, that was certainly embarrassing (don't forget to load the java). The boards should both be visible now.
