Jeff has some additional things to say on this in the comments:
However on the other side and the reason I do still use the all caps and
underscore
Less code? That's a worthwhile cause
deserving of serious discussion.
But whether you call something "foo",
"Foo", "_foo", or "FOO"? Meh.
Naming conventions are highly
controversial and religious.
Developers should pick something they
like, something that's hopefully not
too much at odds with the "local
conventions", and just go with it. A
lot of discussion and hand-wringing
over naming isn't worthwhile.
That said, I think ALL CAPS IS REALLY
HARD TO READ!
I also use this for constants, but I also can understand why some people don't like it. It's a bit like writing everything in lowercase in german or other languages.
