The three mechanisms most important to building such a platform are architecting for extensibility, providing a robust API to the platform’s functionality, and ensuring the long-term health and value of the user experience.
Our responsibilities extend from there. Twitter is responsible for the health, reliability, and scale of the network, Twitter-branded endpoints (SMS, a twitter client on the web and other most popular platforms, Twitter-branded widgets), a consistent user experience, and a sustaining revenue model for the platform. We will provide the best possible experience for each of these.
For this reason, aside from Promoted Tweets, we will not allow any third party to inject paid tweets into a timeline on any service that leverages the Twitter API. We are updating our Terms of Service to articulate clearly what we mean by this statement, and we encourage you to read the updated API Terms of Service to be released shortly.
Secondly, the basis for building a lasting advertising network that benefits users should be innovation, not near-term monetization. Twitter is uniquely dependent on and responsible for the long-term health and value of the platform. Accordingly, a necessary focus of Promoted Tweets is to explore ways to create value for our users. Third party ad networks may be optimized for near-term monetization at the expense of innovating or creating the best user experience. We believe it is our responsibility to encourage creative product development and to curb practices that compromise innovation.
2. We believe there are opportunities to sell ads, build vertical applications, provide breakthrough analytics, and more. Companies are selling real-time display ads or other kinds of mobile ads around the timelines on many Twitter clients, and we derive no explicit value from those ads. That’s fine. We imagine there will be all sorts of other third-party monetization engines that crop up in the vicinity of the timeline.
Platforms evolve. When Annotations ship, there are going to be many new business opportunities on the Twitter platform in addition to those currently available. We know that companies and entrepreneurs will create things with Annotations that we couldn’t have imagined. Companies will emerge that provide all manner of rich data and meta-data services around and in Tweets. Twitter clients could begin to differentiate on their ability to service different data-rich verticals like Finance or Entertainment. Media companies in the ecosystem can begin to incorporate rich tagging capabilities. Much hasbeen written about the opportunities afforded by Annotations because those that understand the benefits of extensible architectures understand their power and potential.
