Interesting infographic here on Pinterest, which tracks with my own personal experience. I see a lot of pinning going on of stuff people want to buy, or dream of buying, which jives with the concept that there’s more brand interaction going on here than on Facebook. That said, I don’t think Pinterest is for every brand. If you sell computer services, well, good luck posting images people want to re-pin. I.e., Pinterest appears much strong at B2C than B2B.
