  This survey shows how, for the Nevanlinna class N of the unit disc, one can
define and often characterize the analogues of well-known objects and
properties related to the algebra of bounded analytic functions $ H^\infty$:
interpolating sequences, Corona theorem, sets of determination, stable rank, as
well as the more recent notions of Weak Embedding Property and threshold of
invertibility for quotient algebras. The general rule we observe is that a
given result for $H^\infty$ can be transposed to N by replacing uniform bounds
by a suitable control by positive harmonic functions. We show several instances
where this rule applies, as well as some exceptions. We also briefly discuss
the situation for the related Smirnov class.
