I am a Pinterest lover from way back! I've been using it for personal things - saving recipes, workout ideas, teaching ideas (from my days as a 2nd grade teacher), etc. but I've been meaning to create a work-related pinterest account where I could save ideas for book displays, storytimes, and programming, books and articles to read, and all other things library related. Here it is if you want to follow me: http://www.pinterest.com/MsDeniLibrarian/
I'm going to try my hand at using Bitly as well. Sounds useful.
