Of course the hour of bot's visit is not important, but it could be important to see if it comes every day or not. Not to mention hits to images and other files.

I'm an author of this article - thank you all for commenting. I don't have an intention to start a flame war - both methods have pros and cons, but in this "GA craziness" people tend to forget that log analysis even exists. Hence the article. :)
And yes, Dataland Software "sells" interactive web log analyzer, but I can't really see how's that important?
