I agree with you. I think overly private CV's are that way because they don't want co-workers noticing or calling them on BS. Of course, some people are just private.

Also, some people, myself included, tend to craft a resume for a particular job. You can always accentuate your strengths that are relevant to the particular job. This is one reason to not post a CV.

I have a very full LinkedIn profile because I use it to market myself. I often include the link in cover letters. I've gotten a lot of callbacks just by exporting my profile as PDF and sending that as my resume (worked for Google). But I know a lot of people just on linked in to keep in touch with co-workers and not to market, so there's no need to list specifics.
