If you’re trying to figure out who to follow on Twitter, you might soon be turning to fellow users for help, rather than the company itself. Evan Williams, the CEO and cofounder of the short-messaging site, said Tuesday that he “desperately” wants to retire or evolve the company’s “suggested user” list, which offers suggestions of people to follow. The list, which was launched early this year and is available to anyone logged in to Twitter, includes people and companies ranging from the actress Kirstie Alley to musician John Mayer to Southwest Airlines.
