Love Pinterest. Wish there was a filter so I could choose what pops up on my feed. For instance: I would opt out of anything to do with 'pig meat' aka bacon, ham, etc., 'paleo', 'Obama', or 'Trump'.
eta: OK. I just found what I needed. Better late than never. There are little x's in the lower right corner of the pins. That will allow me to opt out of stuff that doesn't interest me. Yay!
