Right now Objective Earth is in "Product Design stage". On a weekly basis we are using Google Design Sprint to validate the problems, and their solutions that must be implemented in Objective.Earth.
In 2-3 months we would know the exact features, screens, marketing plans which should go in Objective Earth to make a viral but useful social network.
You can contribute to the Product Design using our github
Once 1st iteration of Product Design is complete, we would start programming this social network. See our phased approach. We would keep it agile - hopefully completing the entire cycle from ideation to implementation in a fortnightly routine.
