Here's what that page currently says (I'm going to assume that quoting
it is covered under fair use):
This collection of hypertext pages is Copyright 1995-2005 by Steve
Summit. Content from the book "C Programming FAQs: Frequently
Asked Questions" (Addison-Wesley, 1995, ISBN 0-201-84519-9) is
made available here by permission of the author and the publisher
as a service to the community. It is intended to complement the
use of the published text and is protected by international
copyright laws. The on-line content may be accessed freely for
personal use but may not be published or retransmitted without
explicit permission.
I see nothing there that precludes discussion, unless you assume that
discussion requires quoting substantial parts of the FAQ. Since the
FAQ is well indexed, a great deal of discussion can take place using
question numbers or hyperlinks.
I Am Not A Lawyer.
Re-posting the entire FAQ would fairly clearly be a copyright
violation. Citing individual questions presumably would not. Quoting
portions of it might or might not fall under fair use, depending on
the size of the quotation and on other factors about which, not being
a lawyer, I won't speculate.
Steve has tended to be reasonably generous in allowing use of the FAQ,
at least as generous as his publisher allows him to be. People have
occasionally quoted entire pages here, with no complaint from Steve.
(Personally, I prefer just to cite question numbers, not just to avoid
copyright infringement, but because it encourages readers to browse
nearby portions of the document.)
