This book in the process of being written is designed to help the  business man thinking of buying a domain for his business.  It will thus enable the domain investor as well.  Very good reading before you buy or sell.

As the Internet becomes cluttered with domains that are hard to remember, keyword domains are going to lead them all.  Keyword domains state exactly what your business is all about.

Domain Packages are a group of domains that provide many portals or entrances to your store. Each domain provides a direct entrance to a certain department in your store.  This provides convenience to your customer because he is able to go directly to what he is looking for.  See Lamp & Lighting Store Domains for an example package of domains.
