Twitter is bringing in a ‘Facebook-style’ algorithm which will pick the best of the site for users – after chilling rumours began to circulate last weekend.

The new-look timeline for twitter arrives Today.  Rumors have been doing the rounds on the internet for a while, and Execs had tried to play down leaked stories about the change, with CEO Jack Dorsey saying, ‘Twitter is real-time. Twitter is about who & what you follow. And Twitter is here to stay! By becoming more Twitter-y!’

But today, when users open their timeline, they will see several tweets from the past several hours that Twitter thinks they are most likely to interact with.  Underneath it they will see the traditional reverse-chronological timeline.

Users can choose to opt out

Users can choose to opt out of the new algorithmic timeline if they wish, or feel that they prefer the way that it use to be.

The change to the timeline, as the homepage is known, is thought to be better designed to appeal to advertisers by giving more prominence to tweets that advertisers pay for, to promote their products.

The change comes just hours before Twitter reports fourth-quarter earnings to investors, who have been pressuring the company to increase user growth and ad revenue by making the product easier to use.

Reports that Twitter could be changing the timeline surfaced last week, prompting laments by users tweeting with the hashtag #RIPTwitter.

They said using a customized, or algorithmic, timeline – similar to Facebook’s News Feed – meant Twitter would lose one of its signature features.
