This is why I read at 0 hidden and always have.
It's simple enough for me to ignore Apps!, APK, Moo, GNAA, whatever, but I tend to find that the mix of trolling to considered posts is nowhere near as off balance as usually suggested.
Losing the ability to post anonymously would undermine a core value of Slashdot. How ironic it would be to have a submission fall under "YRO" and know there would be no anonymous posts within... and this comes from a guy that has posted (maybe) twice as anonymous in 15 years. That said, given the state of things at my job, I've seriously been considering it as of late.
Yes, the signal to noise ratio might be frustrating (or humorous, depending on the mood) at times -- but it's an integral part of the experience. AC wasn't a byproduct of bad design, it was an intentional feature at the beginning. I don't think society has evolved to such a point where it has become vestigial. How can it be, there's a Snowden story on the front page right now?
