I have zero faith in across-the-board competence.

That is, given a possible mistake it _will_ be made.  By a lot of people 
(though possibly a small fraction of the total number of people 
involved).  If the mistake is subtle, it'll be made by a large fraction 
of people.

The majority won't make any given mistake unless the situation is really 
egregious.

A fairly small minority of web authors making a mistake still translates 
to tens of millions of users or more being affected by it.
