Remember when Twitter was just a free and open conduit for whatever content its users wanted to distribute? Those days are long gone now, replaced by Twitter’s desire to control and monetize as much of its platform as possible, and as much of the content that flows through it. The latest skirmish in this ongoing battle came on Wednesday, when Instagram CEO Kevin Systrom confirmed that the service has removed support for Twitter’s “expanded tweets” feature, and therefore photos won’t be showing up in Twitter any more. While Instagram’s relationship with Twitter is complicated, its reasons for doing this should make other media companies stop and think about how they use (or are being used by) Twitter as well.
As noted by Nick Bilton in a New York Times piece and by my colleague Erica Ogg — and confirmed by a post at the official Twitter blog — what Instagram has done is to remove support for the expanded view of tweets that shows up on the Twitter website and in its official apps. These tweets have a special pane that displays excerpts from blog posts and news stories published by certain partners, or photos and videos from certain external services. Twitter originally launched this as something called “expanded tweets” but it has since become a much more ambitious platform called “Twitter Cards.”
