Looks like it's a day of musings for me today... I recently learned about the term "blook". I knew about the phenomena but not that it had a name! The term is either used for a book whose content is based on entries published on a blog (like Just a Geek by Wil Wheaton); or for a book serialized on a blog (like hackoff.com by Tom Evslin). There is even now a Blooker Prize, launched last October by self-publishing outfit Lulu. From what I can see, blooks so far are mostly based on blogs of the personal musings type.
But as more professional blogs are being published; as academics reportedly use blogs more and more to propose, promote and exchange ideas and theories, I'm wondering if there will be blooks based on that content. Maybe academics already do, in scientific publications, without exactly citing their blog as a source of information but using it a source of inspiration.
Finally, a question, would you buy a book for your collection based on blog entries that could be read for free on the Net?
