Well, they won't realise it through seeing their site break in Opera.

I'm glad you are smarter than the average bear, and I am sorry that we  
don't have a reward for that. But in practice, we are forced to decide  
whether it is better to catch the attention of web designers by making  
their site not work (with the incidental cost of catching the attention of  
users who discover that the site doesn't work), or by some other means.

Our experience suggests that the former is simply not effective - and this  
is one of the reasons WHAT-WG began - to deal with the Web in practice,  
and look for ways to improve HTML that didn't require browsers to suddenly  
stop working for reasons that, *to the user* are mystifying and cause them  
to blame the browser.

So yeah, this is clearly a sub-optimal situation and we want to change it.  
That alone won't make the change - which is why Opera pays people  
specifically to go around fixing web sites, code libraries, etc.
