Awesome post Eric
There is a marketer Jeff and I are heavily subscribed to by the name of Seth Godin. He hates spam and "breaking the conversation" in social media with an ad....an ad does not have to be the traditional graphic; it can be a posting by a vendor that is strictly done for solicitation purposes.
The world of sales is different today than it was yesterday folks. The consumer has spoken and you can no longer jump in their face with your sales pitch - you have to earn that right. You have to earn their attention. Everyone is different and every venue is different.
But, I think Eric has nailed how you do it on DealerRefresh.
