Evan, I like where you are going with this and I think you do a diligent job at laying out the landscape, processes (old and new), and some of the players. It's articles like this that should begin the dialogue of what is valuable, what is happening.
My biggest frustration with all of the jibber-jabber (respect to Mr. T) is that the "2.0" and the "expert" monikers that are following the trend of social networks/Web 2.0 are quickly going to become passe - if arguably they haven't already.
What makes sense is what has never happened: sales and marketing to leverage one another regardless of whether the tools are traditional mediums (what does that mean anymore) or new media (uhhhhmmm, can o' worms, right there!)
The "universal" (meaning that it is reported from many analysts) data that has been touted for a few years now that sales teams use or act on less than 10% of what mar/com resources produce is the heralding cry we should all be looking towards when it comes to seeing what's next.
What's next should be a true Mar/Com/Sales Integration, because the tools are really available and the decades old arguments are no longer relevant.
