I just set up a new Drupal installation for a site I'm working on and I have to choose to have a "www" in the URL or not. For now I've decided against it, because it will keep things simple for me when I implement subdomains. However, I have heard some things both for and against the use of "www" in regards to SEO. Also, there's the question of aesthetics and whether it's more popular for users to type it in or not (as I have found, my tech-savvy friends generally don't type it while it's more common among those who are less technically inclined). What do you think? Is "www" dead?
