I think the overhead of paying people to manually update stuff is somewhat under-rated in the article...and what happens when the artist changes their facebook/twitter/myspace/etc... password and you can't get in? How do you convince other sites to use your API? How do you convince artists to switch to your hosting, especially without any existing users? Not a bad strategy if you are HostBaby or a similar existing site, but there are big hurdles for a newbie...unless you have some kind of "in" in the music world.
