- A social media website without a frontend. We just provide a fully exposed API and Oauth, and devs can create their own client to interact with the social network. This would give devs the freedom to create their own experiences without locking users into one specific way of using the social network.
- "Cloud" content hosting as a service. You'd be able to build your own frontend for interacting with a website / blog, and then include our JS code and your site's content will automatically be populated in. This would keep the frontend clean, simple, and cheap, while offloading posts, comments, and other advanced functionality to the service.
Of course both are purely experimental ideas, with no potential real world meaning :D
