Validity of W3C Member homepages over time

Hi,

  Based on http://www.w3.org/Consortium/Member/List I've collected data
on how well the W3C Member homepages pass the W3C MarkUp Validator. The
data from 2004-07-07 to 2004-11-22 can be found at

  http://tinyurl.com/49vrv

The zip archive contains a data.tsv file which has all the data in tab-
separated fields, lots of compressed SVG images generated using Ploticus
showing the number of errors reported by the Validator over time; value
-1 means that there were no results from the Validator (site unreachable
and encoding errors would be common problems that cause this); finally,
there is a all.html file which references all the SVG images. As an
example,

  http://tinyurl.com/5n7u5

would be the chart for America Online, Inc. (AOL). Note that the data
depends on the online version of the W3C MarkUp Validator and may thus
be inaccurate in a number of ways, for example, if the homepage has a
<meta> redirect it checks the redirect page for errors, not the actual
target.

regards.
