How to Find The Average Commenter?

Harmonic or Arithmetic Mean?: I'm trying to settle an argument with my wife - is using the arithmetic mean or harmonic mean more appropriate when finding the "average" number of, say, online comments made by a large number of people, where a significant portion of them make only one comment and a few people make the bulk of the comments?

I'm convinced it's the harmonic mean, which I think gives more weight to the number of posters, as opposed to the arithmetic mean, which I think gives more weight to the total number of posts. Help? Am I right? Would using the harmonic mean more closely reflect the habits of the average poster?
