Revolution.Muslimpad's sleek, modern style includes collections of the latest videos of U.S. military Humvees exploding from roadside bombs in Iraq, as well as pro-jihad messages aimed at radicalizing readers.
But terror experts say it is unique because it is written in English for a Western audience and makes accessible radical Islamic content and context found mainly on Arabic-language sites.
"This Web site is one of the premiere English-language sites promoting terrorism," said cyberterrorism expert Rabbi Abraham Cooper, associate dean of the Jewish human rights group the Wiesenthal Center.
On Thursday Cooper presented a report on Capitol Hill on the dangers Internet sites like Revolution.Muslimpad pose to young, impressionable Muslims. His report, "Digital Terrorism and Hate 2.0," references the Web site four times as an example of how Islamic extremists recruit for Al Qaeda.
