There are typos in Invisible.
Big, glaring (to me) typos.
Has it hurt sales?
Not much.
Has it hurt buzz?
Nope.
Because the rest of the product
is great enough
that readers forgive the typos.
Your product doesn’t have to be perfect
and
it likely will never be perfect.
All it has to be is great.
If it IS great,
stop tweaking and launch it.
