It is a sliding scale for the strength of acids and the strength of the conjugate base. The equation Kw=Ka*Kb tells us what the books says that "the stronger the acid the weaker the conjugate base", and vice versa. However, this doesn't exclude the fact that weak acids will have weak conjugate bases.
