>There's a factor everyone seems to have forgotten...the economy sucks right now. There's a reason why we hear the words "discretionary spending" these days.
But when the going gets tough the tough get going. IOW, in this sucky economy people need to come up with different marketing strategies. Buzz generation is probably the best bet for most publishers of anything today, because it leans heavily on the one industry that is still going strong: the Internet.
As an old fisherman used to say: "If the fish don't come on their own, you have to chum the waters." With the Internet, chum is cheap/free and easy/free to spread far and wide. Circulating a reference book among "domain enthusiasts" might have the same kind of effect in the non-Internet market place.
