Motivation of Open Projects Volunteers

More info is always good, especially when it's about open source. So here's what sounds a worthy endeavour:

My name is Zbigniew Braniecki and I'm a sociology student at Leon Koźmiński Academy in Warsaw.

The goal of this survey is to extend our knowledge about nature of volunteer participation in the Internet open communities. To learn why people participate and what keeps them going.

It will allow us to better understand how open communities (should) work and who the people building them are.

The survey is made of two parts, socio and psychological. It will be most helpful if you make it to the end.

The whole survey will take you no more than 12 minutes to complete.

Thank you for your help. The results will be publicly available on the Interent.
