About 3,500 people are currently using the app, which officially launched Wednesday. The average user spends about 3.5 minutes on the site, Johnson said, who in his day job is cofounder at San Francisco-based developer community Late Labs.
The team is already working to add more features to GhostPost -- at the moment the interface is pretty bare bones -- and scaling it up. On Sunday for instance a location feature will be rolled out to give users a way to either tag where they are or search for chat rooms based on location.
Trending topics, similar to the way Twitter works, will also be incorporated next week, and the developers are also planning to push out dedicated Android and iOS apps for the service within the next month or so. The developers envision a total addressable market of 680 million people.
But at this point the extent to which GhostPost will actually foster creativity is hard to say.
