Well, maybe not forever. But Wednesday's announcement that popular iPhone photo app Hipstamatic can now post their snapshots directly to Instagram's photo sharing network is pretty huge. This marks the first time the Instagram API has allowed a third-party app to add content to its growing social network, clocked at 27 million registered users earlier this month. For developers who couldn't wait for Instagram to publish its API (resourceful hackers reverse-engineered the system back in December, 2010), this could be the beginning of a beautiful friendship.
At the bottom of many blog posts (including this one) and website entries you're likely to find a widget that allows sharing to social sites or emailing to a friend. ShareThis competes with other systems like AddThis and SocialTwist to give publishers an easy-to-install sharing method.
