Awesome thread Brian.
I hope more people jump in....
Here is an idea…vAuto has a merchandising tool that can automatically create custom vehicle descriptions. What if there was a product that could “automatically” create dynamic BLOG posts in one control center that you could export to 10 or 15 different BLOGS. Now THAT I would have to look into!
Alex,
You've described self populating Blog, fed from automatic Comment Generator (CG).
It's Coming! Stay tuned! When you look at vAuto's CG, you're seeing some of my work! While I was working with Dale's fantastic management group, I tried to push them down this road but it was too far outside their business model. :-/
We sell 500-600 used cars a month, For me, it' HAS TO BE totally automatic. Heck, I don't have time to update FB! The easiest place to create a CG is at the inventory source. Because of this, I have been pushing Homenet into this area (for about 3 years). I am deeply involved with HomeNet's CG in alpha.
Here's my personal test bed.
Ford | UsedSUVKing It's a WordPress site, with a Thesis SEO mod (the best WordPress SEO mod known to man-kind), Pages are automatically built from a direct feed from HN.
I've ported in a video feed:
2006 Ford Expedition 4dr 4WD KT1092 | UsedSUVKing for the video walk around. All this data comes via HomeNet's feed, see the Mother page at:
http://www.usedcarking.com/inventory/details2.asp?vehicle_id=kt1092#tippytop
We're almost there... But....It's far from done (is it EVER done?

.
The CG needs to be nested in there, page loading times are pathetic, call to actions need help, the Thesis skin is not auto-shopper friendly, Brian Pasch hasn't worked it over and given it it's blessing yet, I am STILL looking for a method to calculate it's warranty status automatically (another CG add-in). Landing pages need rich content that wont be CG'd. and on and on...
Dealers will be able to buy this turn key fully automatic SEO system very inexpensively. Brian P sells one. Hey! I may sell mine
Stay tuned!
