Very, very useful angles on how/why to deal with reduced support for IE6. Some great data here too on the breakdown of Digg users, by browser, who are active on the site. If IE6 users just read and never push a button, why go to the extra trouble to code buttons they can push?
Definite stuff on hasLayout. In the case I was working on, my mistake was setting a width on a list item. Set the width on the div and the margins on the ul and/or li to avoid all sorts of IE oddity.
Dead simple download to run IE6 for debugging stuff for the 163 percent of people still using outdated buggy wormy icky browsers.
