Godin on Comments
Seth Godin explains why his weblog doesn't have comments. Thanks, Dave Winer!
Not for me, though. First, I feel compelled to clarify or to answer every objection or to point out every flaw in reasoning. Second, it takes way too much of my time to even think about them, never mind curate them. And finally, and most important for you, it permanently changes the way I write. Instead of writing for everyone, I find myself writing in anticipation of the commenters.
Defensive blogging brings its own risks. The gap between "elliptical" and "evasive" can be small, and the difference between privacy and precious coyness can easily vanish while your attention lies elsewhere. But, even if you aren't defensive, the trolls can hijack the discussion more easily than you can defend it.
Let them try it on their own blog.
