Logfile analysis - mainly used in-house where you have access to the server and the logfiles, doesn't take into account caching of browsers
Page tagging- used mainly by people with out access to server, third party hosters, checks an image on a page, takes care of account caching, counts number of times page is loaded
I've been looking at the documentation for installing AWStats and it looks pretty intuitive, not too difficult. I don't have a website of my own to try it out on, I'm not sure what the purpose of having your own website is. I've been poking around the web a little bit to see what most people do for their personal web page. Some people think its a vanity thing, others do it because they feel like they have to grab a piece of "web real estate" while they can. It makes total sense for a company to do, it's great for marketing products, but why would you want to expose your personal life to the entire world? I guess one thing to do would be to provide some sort of unique service to the world through your home page, but I don't have time right now to dedicate any time towards doing that.
