"The three graphs in Figure 2 below were taken from smoothed download counts for existing open source projects on Sourceforge.net"
"A random sample of 150 open source projects will be taken from data provided by Sourceforge.net. Each project will be evaluated to determine their current life cycle stage (where possible) using download counts. Next, the project admins, developers, and several identifiable users for each evaluated project will be contacted via email to request completing a brief questionnaire to measure the current focus of the project, formal structure, division of labor, leader role, coordination, level of commitment, user success, and developer success.
