From Slate:
...thanks to Romenesko's influential readership, every journalistic sin—venial or cardinal—that's published and gets billboarded on his Web page becomes a national story. Everybody from news aides to media moguls reads the site, which is hosted by the Poynter Institute, a gold-plated nonprofit that specializes in remedial education for journalists.
The site functions brilliantly as an ad hoc, post-publication, peer review mechanism for the journalistic profession. It also contributes to journalistic transparency. No newsroom memo or in-house letter of any consequence circulates inside a newspaper for very long before being posted on "Romenesko Memos" or "Romenesko Misc."
Every profession—lawyers, accountants, police, doctors, bankers, et al.—should have such a superhero keeping vigil.
Jim Romenesko's site is irreplaceable because it gives honest reporters public leverage over their corrupt colleagues, their timid editors, their bullying publishers, and their craven owners. Let them transgress, the site seems to whisper.
