We have been testing out one of the first Pinterest services, Pinerly - http://bit.ly/HGNWra , during their private beta.
During their short beta, Pinerly has already started to see some trends on what is now the 3rd most popular social network in the US.
They pulled together this Infographic with some interesting insights - http://bit.ly/Hv08Al - for marketers on how to post to Pinterest for better results.
A few highlights: http://bit.ly/Hv0ebg ;
a. Pinning late at night, past 8pm, is successful
b. Writing a description for each pin is key
c. Use popular boards with high subscriber numbers
