I like the motto that you have because it is true and gets the point across. The only suggestion I would have is to shorten it because I had to read it twice to really have it sink in. Maybe something like: "If you sell or promote a crap product, people will never buy from you again" or you could take the opposite: "I don't have to worry about returning readers because I only promote quality products"
thanks for the great info. I don't know much about blogging yet, but I find a lot of your articles very helpful in explaining the fundamentals. I use it as a reference to answer my many questions.
