Twitter CEO steps down

On a roll

Following several recent successes and changes for microblogging site Twitter, co-founder Evan Williams stepped down as CEO yesterday. Describing the social network as "on a roll", the former CEO's blog post revealed that he is keen to focus more on product strategy.

Evan Williams will now have the job title 'Co-founder' alongside Biz Stone. His replacement as CEO is Dick Costolo, the site's former COO. According to TechCrunch, Costolo ran digital content syndicate FeedBurner until it was acquired by Google in 2007. A new COO is apparently 'not needed', and although Williams will be focussing on product, VP of Product Jason Goldman remains in his position.

Twitter's attempts at profiting from their popularity only began in earnest this year, with the introduction of Promoted Tweets. Williams revealed his new role will focus on "meeting our potential as a profitable company", which perhaps indicates opening Twitter up to more advertising.

140-character marketing

Despite topping 160 million users and 90 million daily tweets, Twitter has had trouble monetising its success. Wired magazine reported that "Twitter has announced plans to inject advertising into its own service next year", as well as signing deals with search engines that would cause tweets to show up in search results. A real-time analytics dashboard has also been implemented to allow brands to monitor the success of their tweets.

Twitter's recent makeover allows users to view tweet content or user profiles, attracting worldwide attention and a predominantly positive reception. In an interview with TechCrunch, Dick Costolo suggested the aesthetic change spurred the management rethink, revealing: "New Twitter was a moment of clarity for all of us here". Evan Williams, meanwhile, seems content with his new job: "Building things is my passion, and I've never been more excited or optimistic about what we have to build".
