I'm usually online 3-5 times a day, when I'm home all day. When I'm doing something else on my computer and the Gmail Notifier tells me that someone has replied to one of my subscribed threads, I usually stop what I'm doing and visit CD.
By the way, if you
really want to see how much you visit CD, in comparison to other people, check out the site stats
here . Click on 'Full list' in the Hosts section, and see how far your hostname is from the top (it's ranked by pages viewed since the beginning of the month).
