This piece left by Kathy Sierra me disturbed. That Ms. Sierra went through this horror is unacceptable to civilized humanity. Yet, what's to be done? Can we reign in these trolls without losing the glorious free speech such venues as Twitter promote? I really don't know. This abuse is what will kill the Internet, of anything will. If the sociopaths win, we all lose, especially the sociopaths. Interesting conundrum.
