Services like Yahoo, Hotmail et. The ridiculousness about the U or ASUU being liable for the postings of idiots is just that, ridiculous. Slash has a much higher profile, a simpler disclaimer, and has had many nasty things posted about people Aaron Thomas would die to meet. It is still up, and as nasty as ever. The disclaimers and boilerplate the U puts up are meant to protect it from such idiots.
Societies have to be able to control their populations, or they quickly cease to exist.
A news site like Slash has to be able to sift the news from the crap, and do so quickly. Otherwise they would not be able to provide interesting content that is easy to find. SOS has inherited that ability through the Slash code. I would say that detractors of SOS fit in two major categories. Those that don't trust the ability of intelligent people to differentiate the relevant and the crap Those whose egos don't allow them to ignore the stupid people in this world.
