Tom Lehrer was right
Don’t write naughty words on walls if you can’t spell. – Tom Lehrer, “Be Prepared”
I was reading a recipe website where some of the esoteric recipes are available for free download, and the more mainstream ones are available at a cost. Unfortunately, the free recipes have obvious omissions in directions – when do I add X to the recipe? How long do I cook this? If the free recipes have so many errors, why should I pay money for the rest of the recipes?
One of the most important things to get right is your free trial. If that doesn’t work, you can forget about getting any paid customers.
