Dear friends, We are conducting a study on the motivation of the knowledge sharing on Wikipedia. Your experience of the read from and write to Wikipedia is very important to the design and management of this knowledge platform. The survey will take about two minutes. We deeply appreciate your help on answering the following questions. After the survey is done, we will randomly select twenty persons and present them with USB 2GB Flash Drives. Besides, with each valid questionnaire, we will donate US $1 dollar to the Wikimedia Foundation. The result of this survey is analyzed in an anonymous way and is only regarded as the academic use. Please feel free to fill out the questionnaire. Thanks again for your time and valuable input. May happiness and health be with you everyday! ★ On-line Questionnaire: http://140.119.19.152:8080/wiki/ 　 Shari S. C. Shang Eldon Y.
