I have have always said that sales (good sales, anyway) is a conversation you have with someone, and in the end they come to share your point of view. So to me, Sales 2.0 is an extension of that conversation where it becomes collaborative for me, the customers, the team, the market, etc. I think it is easier to describe the behaviors of Sales 2.0 than try to define what it is in a phrase or two. Sales 2.0 behaviors:

• Shared knowledge
  • B2B
  • B2C
  • C2C
• Shared selling responsibility
  • Salespeople
  • Evangelists
  • Support
  • Customer-evangelists
• Customer-centric collaborative activity
  • Design & innovation
    
  • Support
  • Marketing
  • Pricing
• Knowledge capture
  • Competitive landscape
  • Customer pain points
  • Solutions

In my view, Sales 2.0 is really about taking the focus off a pre-defined sales process (and even RBS to a certain extent) and using an open and collaborative communication environment to better understand customer pain points and drive solution opportunities.

I chose "none of the above" since "some of the above" and essay write-in were not offered. 

First, I think the notion of "customer" must be re-invented (or obliterated).  What is a customer?  In it's most common definition, it is some notional entity (a person or an organization) that purchases something from my company.  That's very transaction focused.  A few questions to consider: 1) Is there an expiration date on the designation of "customer" - do they continue to be a "customer" if they never buy from me again?  2) What if my organization is a non-profit and someone donates time or money - are they a "customer"?  What if they consume services from my non-profit?  Are they also a customer?  The bottom line is that there are may roles a person or organization will take on over time, based on different contexts.  An org can be a customer, vendor, internal system user, and a competitor all at the same time.  It's valuable to understand all the nuances of the person or org I'm "selling" to.

Second, there are new and powerful social tools that can be very effective at connecting with the right people who what what I have to sell, or they influence people that want what I have to sell.

Third, there are powerful tools to help me understand consumer sentiment of me, my company, and my products / services - as well as those of my competitors.

Fourth, there are tools to help me understand macro/micro economic trends and factors that help to help justify the sale.

Fifth, co-creation and collaboration are a powerful means to get expertise, improve accuracy, and gain buy-in by stakeholders (especially the buyer) to the process, proposal, and justification.
