Twitter announced some new expanded tweet functionality today for users accessing Twitter through twitter.com and mobile.twitter.com. Users will be able to view more content from the tweets themselves, before having to click through to the original site.

I can’t imagine this will help sites in the traffic department, but it certainly makes for a richer Twitter experience.

Essentially, the same functionality that has been available in Twitter for videos and photos, is now being applied to content from a broader range of sites. Before, you may have expanded a tweet to view a YouTube video or an Instagram photo, but now you’ll be able to article previews from publications like The New York Times, The Wall Street Journal, Time, and others, as well as photos from TMZ, BuzzFeed, The WWE, etc.

The expanded tweets won’t work for just any site, but only for select partners. Other partners include: DailyMotion, Lifetime, BET, The San Francisco Chronicle, Der SPiegel Online and MSNBC.

The functionality will soon be applied to Twitter for iPhone and Android.
