I know what you're thinking. Oh man, aren't there enough things in this world to clean? Now we have to tidy up our Pinterest boards? I'll leave it up to you to decide if it's worth your time, but I spent an hour doing some work on mine the other day, and it felt kind of good. I use Pinterest A LOT these days, so the pins build up quickly. The more current and relevant the boards are, and easy to navigate, the more useful it is as a tool. It makes sense to tend it as you would your inbox or other paper files.
