The company isn't commenting on the rumors. However, job cuts wouldn't come as a surprise. Although Twitter is improving its bottom line, there's purportedly a sense among insiders that the firm's programming team is bigger than it should be given the company's growth. Twitter has doubled its headcount in the past two years, but has 'only' added 50 percent more users -- it's not getting a great return on its investment. Whatever the reasons, the layoffs would be consistent with Dorsey's very public desire for greater focus at a company that's seemingly willing to try anything and everything in the name of making money.
