The intro paragraph: 
 
"Once they were hosts to lively discussions about academic style and substance, but the time of scholarly
e-mail lists has passed, meaningful posts slowing to a trickle as professors migrate to blogs, wikis,
Twitter, and social networks like Facebook."
 
Several quotes from librarians...
