The way I see it, the internet is or has been substantially co-opted by liars and charlatans. Now they can spread their BS with a shiny new tool. It has always been and still is hard work to get to the actual bottom of anything.
The liberal organized efforts to rewrite Wikipedia to their world view, including removing the Medieval Warm Period, come to mind.
Editing websites to remove embarrassing or contradictory information is another. For example, the two hospitals that said Obama was born there. It is even easier than the 1984 information cleanup, since you change the code and there aren’t contrary scraps of paper to destroy.
