The speed at which news travels on sites like this is the reason why liberals can no longer dominate the media and control the spin to suit their agenda. The news moves too fast. There are too many people who see stuff and post it, and there are too many smart people to praise it and spread it around if it has merit, and dissect it like a frog in biology class if it's bogus.
That is why I expect some form of regulation, control or tax on blogging. The only reason it has not been done yet is because they haven't figured out how.
