Pinterest, the social media phenomenon, has been cagey about revealing any internal data.

RJMetrics, a business intelligence software company, got tired of waiting.

It wrote a script and analyzed random Pinterest user data.  All in, about 1 million pins were examined.

RJMetrics found a few things worth highlighting:

• Pinterest users post items from an extremely large number of sites.  Etsy items are "pinned" or shared the most, but Etsy still only counts for 3% of total pins.

• Pinterest engages users twice as much as Twitter did at its age

• 80% of pins are repins, or things other user have already shared.

• User interaction is declining, but it's probably because Pinterest has been written about so much lately.  New users are flocking to check it out who aren't part of the core demographic. Thus they lose interest quickly and leave.  Before, Pinterest spread quickly among loyal users -- like moms.

Etsy gets the most pins and repins of any other site on the web. It still only accounts for 3% of all pins.

Naturally, most of Pinterest's pins aren't unique. 80% are repinned, or shared on Pinterest, from someone else's Pinterest page rather than the original source.

40-60% of users still actively pin or share items on Pinterest 8 weeks after they've joined.
