Twitter is the most open application people are currently using. It’s open on the way in and the way out. The variety of applications using the Twitter api are astounding in that they cover many use cases.
Given that, why will Ashton and Oprah someday care?
The problem is Twitter isn’t really open. For Twitter to be truly open, it would have to be possible to use “Twitter” without an any way involving Twitter the institution. Instead, all data goes through Twitter’s centralized service. Today’s dominant core internet services – the web (HTTP), email (SMTP), and subscription messaging (RSS) – are open protocols that are distributed across millions of institutions. If Twitter supplants RSS, it will be the first core internet service that has a single, for-profit gatekeeper.
Why would this matter to Ashton or Oprah? Imagine if Microsoft Exchange server wasn’t just an instantiation of SMTP but was a centralized service that all email had to pass through. A single institution is never as reliable as a system distributed across millions of institutions. Nor is it as secure – for example, a distributed denial-of-service attack can much more easily bring down one service than the entire internet.
But most importantly, having one company control a core internet service hinders competition and therefore innovation. To continue the Microsoft Exchange analogy – do you think in that world we would have such a diverse email ecosystem if everyone had to go through Microsoft to build stuff?
And this is all true while we are still living in the fantasy land where everything involving Twitter is free. At some point Twitter will need to make lots of money to justify their valuation. Then we can really assess the impact of having a single company control a core internet service.
