Twitter’s feed has been living in the past in regard to visual content for years, but now it integrates previews of photos and Vines to bring something other than text and links to its primary means of presenting content. No longer will users have to click through blind links to see photos on the service. Certainly, this is a minor update that should have taken place long ago, but its effects could be felt in a big way as Twitter grows and begins to create a service closer in look and feel to more familiar social media formats.
