"these outages are much more serious. 45 million people worldwide now rely on Twitter as a communication platform" Riiiight. Rely is a very strong word. How will we do business?! How will we talk to our friends and relatives?! Let's face it, Twitter solved a problem that never existed.
That's how new markets are born. Back in the day e-mail solved a problem that didn't exist too.
From Wikipedia: "E-mail predates the inception of the Internet, and was in fact a crucial tool in creating the Internet.
MIT first demonstrated the Compatible Time-Sharing System (CTSS) in 1961.[17] It allowed multiple users to log into the IBM 7094[18] from remote dial-up terminals, and to store files online on disk. This new ability encouraged users to share information in new ways. E-mail started in 1965 as a way for multiple users of a time-sharing mainframe computer to communicate. Although the exact history is murky, among the first systems to have such a facility were SDC's Q32 and MIT's CTSS."
Unless your saying that E-mail wasn't solving a problem since we had the Electric telegraph so we didn't need anything better? http://en.wikipedia.org/wiki/Electrical_telegraph
