Another +1 for prefering tools.ietf.org to ietf.org especially for the
wg pages.
The tools site is significantly more accessible than the IETF site.
One main reason is that the tools site actually uses html heading
elements. Screen readers can easily jump to headings, but I have to tab
through every link in the ietf website's top and navigation to find the
information.
That gets kind of old:-)
mainly pointing this out lest someone argue that the static html version
is more accessible. At least for the blind, it's not.
