Pintrest is a fun site and I, like so many others, can get lost in it. If you like Pintrest, may I recommend Pearltrees? You can use it on the iPad (it's a great app), but it also works perfectly on the computer.
Pearltrees creates a bunch of little webs of interconnected interests of yours. I can't even begin to describe what happens next. You just have to try it. No, I don't get anything if you do, but I'm pretty sure you'll love it :-)
