I’ve been using Pinterest for a couple of years now to keep track of visu­al research. It’s nice to be able to keep the pictures organ­ised in categor­ies, and auto­mat­ic­ally have the source noted. The site is also very visu­ally appeal­ing. If you go to the front page without having any interests or contacts set up, it looks a bit dismal, full of wedding dresses and self-help maxims. However once you have it set to what you want to see (and anything that bores you unfol­lowed), I find it full of inter­est­ing pictures.
