Barry Starr asks on KQED's Quest blog: Why are scientists so scarce in the comments section of most science blogs? Citing the feverish reaction to a recent Quest post on a California vaccination law, Starr posits that scientists stand clear instead of wading into the debate because they are too busy and fearful of becoming targets: "A scientist needs to step up and let people know what the data shows. Unfortunately, this isn't happening right now as much as it should."
