Slate‘s Jacob Silverman is worried about the Internet literary community’s impact on critics’ ability to be honest:
Reviewers shouldn’t be recommendation machines, yet we have settled for that role, in part because the solicitous communalism of Twitter encourages it. Our virtue over the algorithms of Amazon and Barnes & Noble, and the amateurism (some of it quite good and useful) of sites like GoodReads, is that we are professionals with shaded, informed opinions. We are paid to be skeptical, even pugilistic, so that our enthusiasms count for more when they’re well earned. Today’s reviewers tend to lionize the old talk-show dustups between William F. Buckley and Gore Vidal or Noam Chomsky (the videos are on YouTube), but they’re unwilling to engage in that kind of intellectual combat themselves. They praise the bellicosity of Norman Mailer and Pauline Kael, but mostly from afar. Mailer and Kael are your rebellious high school friends: objects of worship, perhaps, but not emulation. After all, it’s all so messy, and someone might get hurt.
Instead, cloying niceness and blind enthusiasm are the dominant sentiments. As if mirroring the surrounding culture, biting criticism has become synonymous with offense; everything is personal—one’s affection for a book is interchangeable with one’s feelings about its author as a person. Critics gush in anticipation for books they haven’t yet read; they ❤ so-and-so writer, tagging the author’s Twitter handle so that he or she knows it, too; they exhaust themselves with outbursts of all-caps praise, because that’s how you boost your follower count and affirm your place in the back-slapping community that is the literary web. And, of course, critics, most of them freelance and hungry for work, want to appeal to fans and readers as well; so to connect with them, they must become them.
Not that there aren’t exceptions.
