Analysis of information sources in references of the Wikipedia article "Javadoc" in English language version.
When I did the original JavaDoc in the original compiler, even the people close around me pretty soundly criticized it. And it was interesting, because the usual criticism was: a good tech writer could do a lot better job than the JavaDoc does. And the answer is, well, yeah, but how many APIs are actually documented by good tech writers? And how many of them actually update their documentation often enough to be useful?
