@scottmcleod - I believe the comment intensity is highly correlated to controversiality AND immediacy. If a lot of people SAW someone recently, they want to interact and comment (immediacy.) If someone says something very emotional or controversial, people want to comment and interact (controversiality.) While I guess looking at these stats are fine, I've found in my very short time blogging that looking too much at numbers of any kind removes my focus from what is important. When I focus intently on conversation, my blog traffic and numbers just grow. I always say "whatever is watered, grows." If I water my investigation of stats, I become a good statistician... if I water my blog but also commenting and participating in the blogosphere as a WHOLE, I become a good blogger. I'd rather be the latter. And while the post was meant to be encouraging... I have to admit I'm a competitive perfectionist and always have to reign in that aspect of my nature.
