Just over two weeks ago, I talked about more interactive experiences within expanded Tweets and how easy it is for users to discover even more great content on Twitter. The technology behind expanded Tweets -- Twitter cards -- gives developers and publishers a way to tell richer stories on Twitter, directly within Tweets and drive traffic back to their sites. Since launch, we've seen great engagement and more than doubled the number of partners that are part of expanded Tweets, and we continue to add more.
