Tarry, I've always been a fan of DIN, I've not seen your Grail solution yet, I'm sure it'll be very interesting to see.
I am a fan of Digital Retailing (DR) as a concept. When it works, DR is the natural conclusion of an online shopping experience.
Observation: DR marketplace penetration is well below estimates.
Thesis: DR's marketplace penetration is dependent on a shopper that is fully ready to buy.
Summary: Digital Retailing's under-performance is OUR 'canary in the coal mine'.
Too many insiders know cars in great detail and don't appreciate how f~cking complex a decision this is. My pal John Q understandably concludes shoppers are lazy. I believe shoppers are selfish and they'll make the best effort they can muster but at some point, ALL SHOPPERS hit the wall *link*. Weeks into the research, they come to realize they NEED to see the dealer to bring an end to this mind-numbing research.
This is why DR hasn't disrupted and why DR's weakness is the doorway into a giant opportunity.
