Addendum: The exception is KiXgolf where you can still use one-character variables.
Other than that, I do have to agree with Erik that especially UDFs should be readable as other might want to uderstand them, too. Just the fact that one posts a UDF normally shows that that person is a skilled coder. So, there's no need for obfuscation.
