Facebook wasn’t the only one interested in purchasing the photo-filtering wonder application in snapping up photo-sharing app Instagram last week for $1 billion.

Twitter co-founder Jack Dorsey was one of the early backers of Instagram, investing in the service in February 2011. Dorsey was also a part of the beta of Instagram and tweeted pictures using the service before it was available to the public, adding buzz around the app’s release.

While Dorsey has posted quite a few Instagram photos over the past year, his Instagram stream has gone silent since the Facebook acquisition of the service.
