I think the critic, as art historian specializing in contemporary art writing, in general, not the artist.
His task, as the specialist, to create (record?) History of contemporary art. Quite a multi-faceted task. He is able to determine how cultural event can be attributed to cultural phenomenon. It can collect and process all possible information on a specific subject: from the directory to the correspondence with artists, tracing their biographies - as far as the imagination. Probably, and the popularization of contemporary art can be included in his task.
And what an artist from criticism? PR. So, just curious. And if a good critic, whose opinion you respect, you can extract a lot of good, paying attention to the marked them work on some points of analysis. Yes, a lot. But this rarely happens.
Yes, but who will open the exhibition? No art-managers also
