Websites To Go Dark For Sandy Hook Moment Of Silence

Some major websites will go dark for one minute Friday at 9:30 a.m. ET as part of a national moment of silence for the victims of last week's shooting at Sandy Hook Elementary School in Newtown, Connecticut.

It's unclear how widespread participation will be online, but more than 100,000 people and sites have pledged to participate on the Causes.com page for the Web Goes Silent campaign. People and companies are also spreading the word by tweeting their intention to go quiet with the hashtag #momentforSandyHook.

High-profile Silicon Valley venture capitalist Ron Conway is working hard to promote the online moment of silence, which is part of a larger campaign for federal gun control legislation. Conway is leading the Causes.com campaign along with other big names including Ryan Seacrest, Jack Dorsey, Britney Spears, MC Hammer, Suze Orman and Tyler Florence.
