The microblogging site just broke out of its character limit for its partner websites. Login to the site and you will be seeing expanded Tweets for content previews, images, videos and other features.

So the users can check out content directly for certain partners inside Twitter, without leaving the web site.

You’ll be able to see expanded tweets for Twitter’s partners like the NY Times, Wall Street Journal, MSNBC’s Breaking News, San Francisco Chronicle, Der Speigel, and TIME will now, without having to click through to their websites.

When you expand any of these news-based Tweet, Twitter will provide a preview of the headline and introduction, as well as the Twitter accounts of the publisher and writer. You can then click through to read the article, follow news accounts, reply or retweet within the Twitter page itself.

It’s not just online news publishers or text that Twitter is targeting with Expanded Tweets. Users will also be able to view images and video directly within the Tweet for other Partners like, BuzzFeed, and TMZ on the image side, and BET, Lifetime, and Dailymotion for video.

The new feature rolls out to everyone on Twitter.com and mobile.twitter.com. For now, Twitter users on the iPhone and Android will have to wait to get expanded Tweets.

But Twitter product manager Michael Sippey wrote on the Twitter blog that users will soon have the same inline viewing capabilities available through native apps for iPhone and Android.

Tweets, including expanded Tweets, still have to be confined to 140 characters. It really doesn’t change the Twitter timeline. It’s when you click on a Tweet and click over the shortened URL that the expanded content unfolds.

It’s Twitter partners that get the extra ability to expand to show additional content after they Tweet. Twitter is trying to be more interactive and engaging to users. This also keeps users on Twitter.com to consume content, rather than immediately clicking through to content sites to read an article.
