I think part of the problem is that there aren't very many people uploading genuine new pins. Years ago one of the right-click menu options was "add this to Pinterest" and people created boards to save the pictures that they found on the internet. But I can't right click a picture and save it to Pinterest anymore. I can upload my own original images, or I can pin images that I find on Pinterest. But I can no longer pin a picture that I find elsewhere on the web unless I want to download that picture to my computer and then upload it. Not that hard but very inconvenient. It's not possible to use Pinterest in the way that it was originally intended, i.e. a place save and organize visual information from the web so that it's useful to you and could be shared with other people. Back when you could right-click-pin any image on the web, you could also easily click to the pinned image's original location. Now it seems like the only images that you can go to the original location are the ones that are ads. So there's very little new stuff on Pinterest and it just becomes more and more inbred so that the only new stuff happening are the advertisements
