No, it is whether someone decides to target you or not, and as linux gets more popular it will be targeted more. Of course user error is a contibutor, but not necessary.
Like I said, the exploits are there if someone wants to run them.
The kernal has exploits as do some of the OS files. Research at CERT if you want to learn John. The first sentence of the article you linked to is a disclaimer about not being a security professional. Trust the professionals more than a blog..
