I think for statically-typed lanaguages like C# and Java, it doesn't actually add any value. Because in most cases, you've got an IDE that'll auto-correct case mismatches for you anyway, so at the end of the day, if I type in "VAriable" by accident, my IDE will auto-correct that to "Variable" for me. Add to that the MyClass myClass; style conventions and you can see that case-sensitivity is not necessarily a bad thing.

For dynamically-typed languages, there might be more of an argument, since it's harder for an IDE to guess an autocorrection, but in the case of dynamically-typed languages, you've already got so much more to worry about (in terms of typos) that using a consistent casing convention isn't going to add that much more burden.

So yes, while there's no real reason languages could not be case-insensitive, there's also no real reason why they should be either.

That article from Scott Hanselman about "SignOn" vs "Signon" was about string comparisons, and nothing to do with programming languages. I agree that strings that users type in should always compared case-insensitively, but I think that's a different ballgame to identifiers in a programming language.
