Last year Dr. Miroslav Stimac asked the Haiku community to participate in a survey to gauge interest in Haiku, usage pattern and wishes for the future, and obtain some general demographic data. This was part of his master thesis "The desktop operating system Haiku" that can now be ordered as PDF or printed book.
Miroslav is so kind to provide chapter 6 with the survey and his analysis as a free download. While naturally being quite technical at times, it offers some interesting numbers that may also become useful when considering strategies in the future. At last we now have some hard empirical data instead of vague feelings concerning size or interests of our community at this point of Haiku's evolution.
