Are you contributing to the general discussion?

A while back, Will Richardson on Webblogg-ed quoted Alan Levin as saying "So how much commenting are you doing [on others blogs]? If you feel you are not getting enough comments [on your blog], are you giving?"
I'm neither satisfied nor disatisfied with number of comments coming to the Blue Skunk (I enjoy the ones that come in, but don't worry about it when they don't). But I have been thinking about Levin's statement in relationship to a unique characteristic of blogging - that it can be more dialog than sermon.
Lately, I've been trying to hold up my end of the conversation by being more diligent about taking the time to comment and react to the ideas of other bloggers.
Should we all have sort of a mental ledger going with our own blog entries in one column and our external posting in another?
