Case study of a marketing blog: Nokia's 7700by
Look how Nokia is using a blog to promote a new phone. It's a textbook example of how corporations are bending the blog format to fit their needs.
LATER NOTE: RECEIVED A MESSAGE FROM THE BLOGGER WHO RUNS THAT SITE. HE SAYS NOKIA HAS A V.I.P. PROGRAM BUT THAT HE SET UP THE SITE ON HIS OWN. MY MISTAKE. I'M LEAVING THE POST IN, BECAUSE IT HAS SOME INTERESTING TRAFFIC. SB
You could make a good case that this site, strictly speaking is not a blog. It's invitation-only (I tried to register and failed.). It's really just a bloggy wing of a very slick Web marketing effort by Nokia.
Forget the arguments about what's a blog and what's not. What's spreading around the world is not the pure blog, but instead a million flavors of bloginess.
