When you hear (or read) something that is SPECTACULAR (like "Betty White dyes quietly at home!), Please check it out before sending it on to your entire contact list! In this case, Betty White COLORS her hair (dyes) at home but many of her fans thought she had passed on (DIED).
General warning: be sure to check out a website that something is posted on! Example: veteranstruthnetwork.com LOOKS like a site that might have good stuff BUT BEWARE! It is FULL of conspiracy theories!
Good places to check out information you hear or get from email include:
Urban Legends (like the 9/11 stories, living shrimp or insects in Chinese jewelry, etc.): Snopes.com or Urban Legends Online. Other good ones in this category are Truth or Fiction.com and Hoax-Slayer.com. And again, PLEASE, before you forward an email to your entire contact list, check one of these sites out to verify its claims!
Fact checking of a more serious kind:
SourceWatch - a unit of the Madison WI-based Center for Media and Democracy, "SourceWatch profiles the activities of front groups, PR spinners, industry-friendly experts, industry-funded organizations, and think tanks trying to manipulate public opinion on behalf of corporations or government."
FactCheck.org - a project of the Annenberg Public Policy Center
PolitiFact.com - a "service" of the Tampa Bay Times
