In the aftermath of the contested Iranian elections, however, it’s been Twitter’s potential as a communications medium, rather than simply a source of up-to-the-minute news, that has been front and center. It’s usurped Facebook as the social-media tool in the spotlight. The U.S. Department of State even requested that the company reschedule a planned outage so that it would be less likely to disrupt the flow of information coming from Iran. (…) If Twitter is going to continue to have this kind of role in international affairs, it’s going to need infrastructure so rock-solid that it drives the “fail whale” into extinction. It will need to hire employees with expertise in public policy and communications and a legal team capable of handling issues much more serious than a ticked-off baseball team manager. Those things take money, and this is a company whose co-founder once hinted that hiring an advertising sales staff would be too labor-intensive and costly.
Twitter grew faster than blogs, which grew faster than instant messaging. FriendFeed is growing faster because it sits on the back of Twitter. The next thing that comes along will grow faster still.
