Still, most haven't read the incomplete bits either :-)
Manuals constantly need updating, along with examples needing to be
updated too.
True. And that is a lot work. OSS answer to that is highlevel parallellism to manuals, but in practice that gives crappy manuals.
Makes me wonder what PHP people were thinking, adding a silly comment system to
their main documentation URL's. How can that help anyone. The manuals are
already complete, and set in stone. They don't change.
We have this with FPC too (select with comments),
http://community.freepascal.org:8080/docs-html/ref/refsu47.html#x113-12000010.3.6
this is mostly to submit feedback back to the doc maintainer(s) on a per subject basis, and avoiding a lot of routine work on maillists etc.
That doesn't mean the lists can't be used for communicating over the docs, but for trivia the comment system could be handy (though I never heard back from Michael how it works in practice, and _if_ there are any submissions)
