Being listed on Network will drive more traffic to your site. Displaying the Freedom Engineer Banner on your own site allowing visitors to know who you are will give you more credibility. You can learn from and exchange knowledge with other engineers. You will most likely become friends with other engineers. They are introduced to new freedom engineering information - goods and services that they would not have been other wise.
More engineers mean more selection.
They may find an engineer in their geographical area. I could not provide for a fraction of the demand myself. Not only do I teach others - I also learn a great deal from you. The more engineers are in the network the more weight the title has. By building a network I can help spread freedom through out the earth much faster.
