Twitter has started rolling out an Activity tab that gives web users an overview of what others are up to on the site.

The feature, which is similar to Facebook's News Feed, allows users of the micro-blogging service to see new followers, retweets and even their posts that have been listed as 'favourites'.

Twitter initially began trialling the feature in August this year.

"It [the Activity tab] provides a rich new source of discovery by highlighting the latest Favorites, Retweets, and Follows from the people you follow on Twitter – all in one place. It's easier than ever to explore Twitter, connect with people, and discover what's happening around the world," the micro-blogging service said in a blog at the time.

To access the new feature, simply press the Activity tab that appears at the top of the main home screen when you log-in to Twitter. While the roll-out has begun, Twitter has not revealed how long it will take for it to be completed. However, as soon as the tab is made available, you'll see a bubble alerting you to its presence.
