SAN FRANCISCO (Reuters) - Twitter Inc unveiled a redesign of its user profile pages on Tuesday, the latest in a series of steps promised by the company to bring new users to the seven-year-old service.
In response to an all-time low in user growth figures during the recent quarter, Twitter Chief Executive Dick Costolo told worried Wall Street analysts that the company would make a number of changes to freshen up the service.
Tuesday's redesign, while mostly cosmetic, hinted at what Costolo described in February as a willingness to experiment with new ways to organize content. Users can now "pin" a tweet to stay at the top of their feed, a rare instance of Twitter departing from the continuously rolling format that has defined the service.
Tweets that have received more retweets or replies will also appear slightly larger to spur more user engagement.
The new layout, which will be available to a small group of users initially, will be widely deployed to Twitter's 241 million users in the coming weeks, the company said.
Twitter reported higher-than-expected fourth-quarter revenue on February 6, but investors focused on user growth of just 3.8 percent, the lowest rate of quarter-on-quarter growth since Twitter began disclosing user figures. The San Francisco-based company went public in November.
In recent weeks, Twitter has also reportedly been testing a number of new advertising units, such as ads that include download links for mobile apps.
As part of Tuesday's refresh, Twitter said users will also be allowed to select a large banner picture to display across the top of their profile page, as well as a much larger profile picture, two features that resemble another social network familiar to most of the world's Internet users: Facebook.
