Twitter gets a facelift

Twitter unveiled a redesigned website Tuesday that gives users the ability to preview pictures and videos and see information about the authors of tweets.

Chief executive Evan Williams announced the changes in a blog post promising users an easier, faster and richer experience. The changes are the first major redesign of the fast-growing micro-blogging service, which was founded in 2006 and has 160 million users worldwide.

The new site will allow users to see photos and videos embedded directly into their Twitter streams through partnerships with media-sharing websites including Flickr, YouTube and Vimeo. Users will also be able to see mini profiles containing information on the author of any particular tweet.

The new features will be rolled out incrementally during the next several weeks, with each feature debuting to a select number of users first before spreading to all users. The site's homepage will also undergo a redesign to ease navigation.
