The first announcement will interest mobile application developers. In fact, you may have heard of Twitter Cards (or extended tweets), which is the feature that will show an image, a photo, a video or an article summary directly from the Twitter.com interface. Its use could become widespread in the near future with names like Flickr, Path, Foursquare and Etsy who had the privilege to incorporate a little early. Simply put, if a person shares a Flickr photo on Twitter, you will be able to view the photo directly following the updates on your mobile application.
If you have Flickr app on your phone, a link at the bottom offers you to see the photo in the application, and if you don't, you will be prompted to go and download it.
Twitter could so quickly become a new download source for application developers.

Summary Card: information for sites that wish to put the title of an article, the lead-in, a small image and logo of the media.Photo Card: to include one photograph in a tweet.
Card Gallery: to include up to 4 photos in one tweetApp Card: to transform iTunes links and Google Play in descriptive card applicationCard Player: to include a video in a tweetProduct Card: To add a product to an online e-commerce site(as with the example Etsy)
The Twitter Cards are good news for Twitter, which will make it more complete flow and therefore more interesting AND good news for developers who are going to benefit from it to increase their traffic, download applications, or sell products.
