I agree with this.  As an excessive previewer myself, the mental  
model that lives in my head assumes that previews are volatile.  I  
preview because I don't want to save my data before it's ready to be  
saved.  I don't finish everything that I start writing so every once  
in a while, I abandon the post in which case the previews and the  
node ID would still be in the database?  That said, I'm not opposed  
to an auto-save feature or a 'Save as draft' feature.  Except that it  
should somehow align better with my mental model.

Something else to consider -- spammers will often try to submit spam  
to your site. Even if they don't make it through, they might insert  
permanent junk in your database.
