There are a lot of high profile celebrities and brands on Pinterest. You might not be familiar with them if you aren't interested in high profile celebrities and brands to begin with.
So I have to ask, as someone that hasn't used pinterest, have any suggestions? I'm a guy but whatever, I just want to see some of the interesting stuff that drives certain people to it.
There really aren't any interesting superbrands nor celebrities there - especially for guys - but I found a great Pinterest profile that tries to track all the major brands and celebrities present on the site: http://pinterest.com/pinterestpower/.
