Robert Scoble just finished a half hour interview with Twitter Founders Evan Willams and Biz Stone. The two are surprisingly candid about the scaling problems the service has had since, oh, it launched two years ago.
“The fact that people are frustrated is a sign that we built something people care about,” says Williams a few minutes in. I agree, but that’s no way to run a business. Stone also says that Twitter doubled in size in March/April this year.
