Should we create diversified name selling sites

As some of you know, I started a project to attempt to sell my names to a broader range of end users, and therefore to see if I could increase the return on my sales portfolio. The project was called -
Wise Accountant
It's very much an embryonic site at the moment, and very much a personal experiment. I'm trying to do a number of things.

• Increase awareness of the benefits of a good domain name
• Expand the market by promoting the purchase of traffic generation names
• Explaining the advantages of investing in virtual assets.

This thread is intended to be a discussion about educating potential buyers, and not really about my experimental site - although comments are always welcome if they will help me to improve the site.
I feel that simple lists of names are really just selling to the converted, and don't contribute to the expansion of the market.
