Twitter's Costolo launches 'instant timeline' so you don't have to follow people

Twitter is to roll out an "instant timeline" to "remove all that friction for new users." The product will let consumers see what's happening on the site without having to first follow people.

This was revealed by Twitter chief executive Dick Costolo at the company's first analyst day in San Francisco today.

He said the company will unveil products to attract new users and others who don't normally pay attention to the microblogging service, as it works to extend its reach beyond the base of regular users.

Costolo also said the company is working on new mobile applications besides its Vine video-sharing app and added that more than 500 million people come to Twitter each month without logging in.

Twitter's ad revenue has risen steadily, reaching $320m in the third quarter, a 109 per cent annual increase.

But the company, said Bloomberg, is on a mission to "explain its prospects" to appease investors who are disappointed after several quarters of slowing user growth .

The question: Will Twitter ever reach the scale of Facebook, which has 1.3 billion members or about five times that of Twitter.

Costolo has prioritised improving the company's product even if users are logged out of the service and coming into Twitter via a link to a tweet, or to view someone's profile.

Twitter's monthly active user count rose 23 per cent to 284 million in the third quarter, down from 24% growth the prior quarter.

The company went public at $26 a share last November and the stock has been under pressure this year amid investor questions, said Bloomberg.

Costolo has replaced several top lieutenants, including ousting his chief operating officer and appointing a new chief financial officer and head of product.

"People are on Twitter because they like to see tweets, but they need to curate the site to engage the casual reader, who just want to easily find these important nuggets," Walter Price, a portfolio manager at RCM Capital Management, said today on CNBC.
