Can someone please explain how can news aggregator sites like Techmeme or Blogrunner do not run into copyright infringement issues? Aren't they simply taking content from other websites/blogs and publishing it on their own websites? Sure, it brings traffic to those sites and I'm sure none of the smaller blogs will complain. But how about bigger blogs or corporate websites? Could they do anything? In fact, thinking about it, it's just like any search engine. Theoretically, Google could be sued for illegaly making copies of copyrighted content to their DB and indexing system, and publishing it on their website. Moreoever they make money from the ads displayed around this content! Isn't this something against the AdSense TOS Please someone, enlighten me.
