Don't think defacements take skill or talent.. usually they take a Bugtraq posting and a kid with too much time on their hands.
I agree with this about 99% of the time. There have been some high profile defacements that actually required some time. Nothing like zero bugging if you are the zero bugger!!!

Knowledge, responsibility, and intent are all factors here.

It is far easier to destroy than it is to protect.
