Last I checked, you could have up to 6 boards set as 'secret boards' on Pinterest.
What's up with the secret boards on Pinterest anyway?
Well I guess the answer is that, as a social network, Pinterest main objective is to get people sharing and being social... So doing things in secret or anonymously doesn't make much sense.
I'd keep an eye on Pinterest in the next few months though. Word is they're rolling out new features, so it might be worth seeing what happens next with one of the world's favorite image sharing social network.
