One of Twitter's founders has labelled calls for CEO Dick Costolo to be fired as "crazy" and said the criticism he faces is like "water off a duck's back".

Biz Stone, who is currently promoting his new app Super, told IBTimes UK that at standing monthly meetings with Costolo they joke about the criticism which he and Twitter as a whole face from people if they miss quarterly revenue and growth targets.

Speaking about the people who recently questioned Twitter's revenue-generating potential, Stone said: "I don't actually know anything about those things and I tend to think in the longer term. You are talking about people who think quarterly and if [results are] a percent off that quarter, it's like: "Fire the CEO," and that's crazy."
