Digg.com How is it legal to copy content onto this site?

Can someone enlighten me how digg.com works (legally speaking).

Could someone copy a news story text image or video from msn.com, yahoo.com latimes.com or youtube.com and paste it onto digg.com?

Digg.com makes money from others content.

Thanks.

 

Ain't it same with other search engines. Similarly aint it same with facebook etc all social bookmarking sites.

 

Basically, it works as though you are writing a research paper. As long as you cite your sources and give credit back to the original author, then legally speaking, you can do this. Plus, they are only publishing an excerpt from the content or a review of it.

Thanks for all of your input.

I will read through that internet law link.
