wikiCIC is something we hope to roll out in the near future.  It is a wiki version of the book, which means it is a version that anyone can edit.  This is somewhat of an experiment but we believe a worthy one.  We certainly don't claim we know all there is to know.  On the contrary, we consider input from others as critical to this project.  One way we are doing that now is by incorporating comments submitted by readers.  A more dramatic experiment, we call wikiCIC, would be to let readers edit the text directly.  Should be interesting.
