Pinterest, the fastest-growing social media site nowadays (especially with it being no longer invite only), is rapidly being used as a way to share (or pin onto a board) your favorite items, sports teams, food, and even political viewpoints. Even a few of my favorite left-leaning news sites, such as TPM, Raw Story, Media Matters, Current TV, and Think Progress, have Pinterest sites.
Both major parties have Presidential candidates (Barack Obama [D], Mitt Romney [R], plus Libertarian Gary Johnson) that use Pinterest, as does Mitt's wife Ann and the FLOTUS Michelle Obama.
Both major parties have Pinterest boards as well... the Democratic Party and GOP.
I have a Pinterest board on the 2012 Elections, News, and Politics in general.
I honestly believe that this site should have a "pin it" button.
Anybody on Kos have a Pinterest account?
