I've had a website which hosts my projects (since just after the dawn of the web), it has always been a portfolio (aren't all personal sites?) but implicitly. All of that time I've made a point of never saying anything about myself. First because I don't think anyone would really be interested, secondly because it's none of their business, but mainly because I think the work should speak for itself. So plenty of text, but text which describes the work in question.
Just my take on the portfolio website: sometimes less is more. You want to know more about me? Invite me to an interview :-)
