Every so often a journalist draws criticism for something he retweeted. And whether that criticism is justified or not, it discourages some journalists from using Twitter effectively.

Jeff Sonderman outlines the way that journalists are now using Twitter to retweet information, and some of the pitfalls each of the methods has when it comes to erasing the appearance of bias.

Ultimately, Sonderman suggests a new class of retweets for journalists and others who want to relay information on Twitter without specifically endorsing or offering the appearance of an endorsement: a “neutral retweet.”

It’s an interesting concept. But in practical terms, I doubt even that is enough to dissuade some readers with an axe to grind to assume the journalist has a bias, anyway.
