[GreenKeys] Upper Case v. Mixed Case readability

[Tim McNerney]

Indeed, there have been studies that strongly indicate (in the general
population at least) that mixed upper and lower case text, and even lower
case only text is easier to read than text in all caps.  Lawyers and
cigarette companies take advantage of this fact.  If they don't want you to
read something, they print it in all caps.  That said... I am sure that,
with the training and years of experience, many members of this list could
skew the results of any of these readability studies. :-)
