I still don’t pin, but once I get around to it, and have an About Me, I’ll probably pin as you do. I just want to say thanks to all who keep an open mind about the pins—I search for dates which is the only way I can find the latest published article.
2-3 pins sound reasonable to me, but hey, if 5 is what tickles someone’s fancy—why not! It’s a matter of personal preference.
