I was just finishing up our guide to how to optimize for search suggestion, and noticed something worth discussing.
I am not sure if safe harbor covers companies that index content, cache/host content, and suggest searches for downloading pirated works...but if it does, I think the law needs changed. It seems Google could have thought about the torrent related keyword suggestions before launching search suggest as a default.

Part of the reason why I had to change my business model was the need for a more interactive higher value service, but another big part of it was also that I saw this sort of activity coming. It is too hard to create valuable information and sell it in a digital format unless it is broken up into pieces, is time sensitive, and/or has interactive elements added to it.
If you think Google respects copyright you are wrong. All content wants to be free, and, preferably hosted by Google, wrapped in AdSense.
