Petrossian’s essay "Antipoetry, or When the Does Not Seek an Alibi" has aroused intense discussions in Armenian literary circles. In this essay, Petrossian speaks about "antipoetry"—poetry that does not look like poetry and challenges the prevailing notion of poetry—and asserts that it is the leading tendency in contemporary Armenian poetry. Marine Petrossian is largely known in Armenia also as a columnist.
In 2007-2009, a period of tense political developments before and after Armenian presidential election, 2008, she led a weekly column in Haikakan jamanak (Armenian Times) daily, the main opposition newspaper.
Her essays on political issues of the day had an unprecedently large readership and made her a public figure in Armenia: many television programs invite her to comment on public issues. These essays later were collected in her book Red Poster (2011).
