I think that people are likely to confuse rules and triggers. The other 
issue is that they are not documented in such a way as to make them 
simple to understand. But beyond that, although I like Neil's 
suggestion better, rules work pretty well for what I need them for--the 
ability to INSERT, UPDATE, or DELETE on a view.

Come to my presentation at OSCON this summer to see what I'm doing with 
them. :-)
