On one of my queries yesterday, suddenly 6 Pinterest boards jumped onto page 1. This is really strange. They all have pins going to my page and various others, which they now outrank. So, my Google traffic is dismal as it's been since Penguin, but my Pinterest traffic is way up... driven by Google.

That's just bizarre, IMHO. For 6 Pinterest boards to be on page 1, and all linking to the same stuff (so they're not even easily distinguishes from each other)... that sort of thing really irritates me as a searcher. What is Google trying to do here?
