See Kevin’s post about Google obviously censoring real search terms from his site. How can a site owner gauge whether or not this is happening to their website and what methods can be used to circumvent it?

What alternate (technical) explanations could exist for this, as opposed to outright censorship?

Two mission critical items:

1. Begin backing up and printing out your friend’s websites
2. Maybe it’s time we begin seeking alternative methods of information distribution which are not so easily controlled by centralized technology. Suggestions?
