Are vendors missing it in the Blosphere

I have only witnessed a few good blogs from vendors in the automotive industry.  Major institutions are missing it bad. (Article I did about this).

Here is a list of important blogs in my opinion:

• Our website is set up on a blog platform and concentrates on automotive seo strategies.   We provide tactical information without a pitch.  Of course I would include it in this list.
  
• Activengage's blog that discusses many things not just dealer chat.
• Many of the participants on the Drivingsales Blog there is a good mix of content like this story about paid dealer reviews, while at the same time many who contribute still write a whole lot of nothing.
• Jeff Kershner's Dealerrefresh is not vendor created but is supported by vendor advertisers.  Lots of good information there too and should not be left out.

Please comment and leave your suggestions as well.
