Pinterest? Be Afraid! Be very afraid! It is ADDICTIVE and you can spend hours just scrolling, looking and scrolling and looking and looking.... It's like a huge catalog-encyclopedia-fashion runway-recipebook-travelogue-atlas-..... etc.
I do not "pin". There is not enough cyber-space on the cyber-bulletin board to hold all my "likes". I get pleasure from looking and dreaming, if there is something special (recipe or design) I'll note the webpage or save the photo.
Yes, and beware of the public domain., but enjoy the "trip".
Caveat Emptor.
