I’ve assigned a substantial portion of Dan Gillmor’s We the Media
for class this coming Monday in Internet, Law and Politics at Harvard
Law School.  Turns out that the book is sold-out of most of the
Harvard Square bookstores, checked out of the libraries, etc. 
(Not to worry; we’ve ordered some more.)  What is so cool is that
it’s not a problem: Dan and O’Reilly have offered it free-for-download, in its entirety.  How cool is that?  No scarcity, even when there is scarcity.  No one will go unenlightened!
