Rebecca Rosen highlights a new tool to target the forwarded BS in your inbox:
LazyTruth [link] is a plug-in for Chrome that automatically scans email for information that FactCheck.org and Politifact have deemed false. If something doesn't check out, it'll provide a few words of correction and a link to where you can find out more. You can then easily pass that verified information on to the email's sender. Down the road [developer Matt] Stempeck plans to add more kinds of rumors to LazyTruth's filter — urban myths, hoaxes, false security threats, etc. — but for now the tool is limited to political tall tales.
