who are your most frequent commenters?

I've never tried to focus on writing what will get comments - I really want to write about what moves me. Which is why there honestly aren't all that many visitors to my site. (although it is growing, slowly) What I do find amusing is that while I've finally started getting some pariticipation on the site, my most frequent commenters are my son Trevor's friends from school. I'm flattered that Nick and others are reading the posts, but I do hope I can convince others to weigh in on some of the topics I've written about as well! So I'll end with the beginning, and ask again: who are YOUR most frequent commenters?
