I agree that selling to SMBs and Enterprises are very different approaches.
We are still in the customer development phase (http://www.startuplessonslearned.com/2008/11/what-is-custome...) and really want to "get out of the building" to start learning about whether our assumptions are right.
I am not really sure how to approach the organizations. Is face-to-face a better option or online networking is better?
