Reporter, please keep it one bug per bug report.

The washington.edu has bad JavaScript code:
[...]
if (document.layers || document.all)
    document.write ("<script src='/home/scripts/flyout.js' "
[...]
Should be moved to Tech Evangelism.

jessett.com WFM.

mbusa must be a background image causing slowliness.
