fooBarBaz is more readable than foo_bar_baz?!
Are you serious?
fooBarBaz has the shape of a single strangely capitalized word.
Finding where each word begins and ends is far from obvious.
As said in other post, the shape is important, so spacing is important: 
underscore is the better way to keep spacing while getting the compiler 
job done easily.

Humans - even programmers -
are more accustomed to reading words without underscores (which are not
always easy to see anyway).
Note also that some emacs programming mode display underscores within 
identifier as spaces.
But i don't think emacs mode guessing where to add spaces in identifiers 
like fooBarBaz exists. Could be funny with acronyms :-)

Besides, fooBarBaz has two fewer characters to
type!
 

Yes, but trying to spare keystrokes leads to the most unreadable 
langages, this is the root of all evil! :-)
