Kimee, the quick hack fix is to change the one line of javascript that
modifies the font size based on scale. You will find it in the file
cloud_facet.js, the line is
elmt.style.fontSize = Math.ceil(100 + 100 * Math.log(1 + 1.5 *
(entry.count - min) / range)) + "%";
if you replace this with
elmt.style.fontSize = "100%"
you will get what you want.
long term will should scalefactor as an option for the cloud facet
