I don’t know what the folks over in the Pinterest promotions department are doing, but whatever it is…it’s working! It seems that the site has exploded just in the last month and having mentioned that I’m a Pinterest addict on FaceBook multiple times, I have received many questions from family and friends over the past few weeks. What is it? Why should I join? How do I join? I requested an invite, but I haven’t heard back. Etc, etc.
