Hi there,
I'm a researcher studying software evolution. As part of my current research, I'm studying the implications of open-sourcing a proprietary software, for instance, if the project succeed in attracting newcomers. Mongodb was in my list.
To further analyze the impacts of Mongodb migration, we analyzed the git log commit history of your project in terms of number of contributions, number of newcomers, and number of contributors per month. The following figure presents a temporal perspective regarding these three measures.
Given the numbers presented in the graphic, we would like to ask Mongodb developers the following questions:
1. What motivated the project to migrate to Github? How do you evaluate the benefits of this migration?
2. Does this snapshot make sense? Did you find any inconsistency on the data?
3. Do you have any internal policy to promote/attract/retain newcomers? If so, do them succeed?
4. Although there is a steady flow of newcomers joining the project, we found an increasing number of contributors in the project, which differs from the other analyzed projects. Is there any explanations for this high newcomers retention rate?
Thanks in advance for your collaboration,
