Tight Sphincters

Dan Gillmor has a right to ethically challenge the ethically challenged and any others who might want to sign on to his Bayosphere as armed and badged "community journalists."  Jeff Jarvis says, "Still, I'm not sure I want to go signing any pledges. Signing a pledge doesn't make me more trustworthy or more accurate or more decent or more ethical. Either you trust me or you don't."  I think this whole matter was resolved in the 17th century.  I agree with Jeff that a pledge is superfluous.
