#4 Invest in tools
#5 Establish ownership
#6 Gamification of good behavior
1. How core to Facebook's business is this technology?
2. Who will use it? Who is this technology useful to? How valuable is it?
3. What else already exists that is similar to this technology?
4. Is there anything novel in this project?
5. Does it include any third-party code, including any third-party open source?
6. Who will maintain the project, accept contributions, and liaise with the community?
7. Where & how should this project be distributed?
8. What is your expected public release date?
