Open source software is very good, but ease of use is indeed insufficient. Today, I debug JSPWIKI, I have found that I have misunderstood the contents of Readme's install part.
I think INSTALL is the most important part, unfortunately, these software authors (technical experts) do not seem to pay attention to this face project.
Microsoft is known for its ease of use, this worth opening source software learning.
This may be an important research topic!
