Twitter has updated the design of its Discover tab to include the new Twitter Cards feature, which expands the content of tweets like articles and images. The new Discover also streams tweets on the page.

The Twitter Cards feature has been rolling out to partners on a limited basis and the Twitter-owned Tweetdeck just got support for it this week. Bringing the Cards to the Discover tab makes a lot of sense.

Streaming the Discover tab is interesting, as the home page currently does not stream tweets at all. Of course the tweets rolling into the Discover tab will be coming in at a much slower rate than your main stream will be, so it’s a different use case. Twitter is obviously trying to give people more reasons to visit the Discover tab, and one way they’re doing that is to ensure that there is always something new to look at on the tab.

The Discover tab was launched back in December of 2011, with ‘New Twitter’, a redesign of the original Twitter experience that also added the Connect tab which tracks mentions and interactions. At the time, Twitter billed it as a way to “see results reflecting your interests—based on your current location, what you follow and what’s happening in the world”

Twitter says that the new Discover design is rolling out gradually to everyone.
