Motivating community for starting Open Source Projects

Open Source Projects are, indeed, not far from other type of associations or companies where motivation is a key.

Community building is important for already existing projects with strong communities behind.

However, starting Open Source projects are also challenged to show what the project offers, the kind of beneficiaries this project should have, technology , members of the project, and so on and so forth.

I would like to share a nice motivating video on how to "sell" to the community a starting project, in this case, a project hosted by the Linux Foundation, the OpenDayLight Open Source Project [1]:

The video, from my perspective, it is interesting as a good example of community attractive video because of next reasons:

1 - It is concise.
2 - It shows the motivation of the project clearly.
3 - It is "smart" and graphically attractive.

You work as computer engineer or as network engineer. You know Big Data, Cloud Computing and SDN will be the future technologies. Don't you feel a little bit motivated to participate in the community after watching the video?
