Hey Sam,
I am going to venture a guess and say the "buzz" could amount to the difference between a $5000.00 profit launch to a $35000.00 launch.
Or for a better more concret example. My friend Dave launched his product with over 100 JV partners and earned 265K within 25 hrs.
So I don't want to dwell on the money aspect but more importantly the relationship side of creating these partnerships and being able to offer some value and to echo what Kim has outlined already.
Take Care
Todd
