Excellent review in Friday's Wall Street Journal (this is my long weekend) that reviewed four of the more popular web sites devoted to urban legends.
In order of the rating given it by the Wall Street Journal:
4) About.com's Urban Legends Guide - one star;
3) UrbanLegends.com - 2.5 stars;
2) The Straight Dope - 3 stars;
1) Snopes.com - 4 stars.
The only one that I send you? The one that got four stars.
BREADTH:
"Snopes.com offers the most extensive collection of urban legends among the sites that we checked."
DEPTH OF INFORMATION:
"Site founders Barbara and David Mickelson research the answer to hundreds of legends, rather than relying on other Internet sites or news groups (Dan's translation = they read books), Snopes.com offers more background information and definitive answers on the veractiy of popular rumors than any other site we looked at."
ENTERTAINMENT VALUE:
"Although not as funny as some of the urban-legend sites, Snopes.com is entertaining because of its sheer size - almost any urban legend you have ever heard of is mentioned here."
OVERALL USEFULLNESS:
"Snopes.com is the easiest to use of the pages we reviewed: the categories are sensible and easy to navigate, the site is regularly updated and offers up-to-the-minute information on a variety of hoaxes."
