I added rel=nofollow to my comment links. More info at Six Log: Support for nofollow.

Update: John Batelle weighs in on nofollow
My gut take on this yesterday was "We're making a decision without thinking through the implications." My second gut take was "We can't possibly imagine all the implications." So my third gut take is "Don't do it if we can't imagine what consequences it might have."
I think John's reaction assumes that the big search engines are the only "processors of our collective reality," and that any change in how they operate represents a major change in our collective reality. I think the nofollow tag puts more control of search engines into the hands of content-controllers. (eg. hosted weblog services, ISPs, etc.) This means there's less control for people who contribute content, but don't own and control their own web space. I'm not sure how I feel about the implications of that (not good right now), but I also know that comment spam is a serious problem and something needed to be done before all discussion stopped.
