I think it's a matter of balance - at one extreme is IOCCC-style excessive terseness+obfuscation, and at the other extreme is the type of excessively indirect code often referred to as "enterprisey". The average probably varies depending on the culture of the language (contrast the typical C project with a Java one, for example), but over the years I've found that as my skill with a language improves, my code tends to become more concise.

Whenever someone brings up the "cleverness" argument I always like to mention this counterpoint: http://www.linusakesson.net/programming/kernighans-lever/
