Michael Arrington may come off as pompous to some people but the truth is he really knows his shit.
Read this post for some insight why old, dead tree media is dying. Basically the summary is that Fortune asked Arrington to publish a post giving some book (which I won’t be naming here) some publicity, they even sent him some excerpts to use. Arrington obliges, posts a rave review, the excerpts he was sent and prominent links not only to Fortune’s site but to directly buy the book.
I don’t need to go into that much detail here but definitely check out this post if you want to know why print media is circling the drain. They’re all staunch walled garden publications that will do anything to not see their content, even excerpts of it, anywhere else on the web no matter how beneficial.
