Idiot/Savant has given up on on comments at his No Right Turn blog, joining a slew of others who've shut down feedback. I/S blames "an influx of trolls, who have established a toxic and abusive atmosphere and progressively drowned out those commenters who actually have something interesting to say." The last straw seems to have been this thread. "Some of you," he says, "may be unhappy with this decision. I'll simply point out that this is my blog, and that if you don't like the way I run it (or what I say on it), you are perfectly free to start your own."
Fair enough; it's entirely his decision -- even if it does remove one of the most useful parts of blogging, which is the ability to be apprised of and to correct mistakes (something demonstrated on that very thread that offended him). For myself, it's worth recalling that free speech doesn't require that you provide your attackers with a microphone, and I have to say that in the main I've been very lucky with my commenters here. Most of you do need a lot of work, though. :-)
