There are some applications for which queries based on typed user input 
are rare.  But there are others for which those queries are the basis 
of the whole application!  Almost any kind of site where users are 
creating accounts and other data records (or their equivalents) will be 
like this, and that's a very common kind of web application.

I agree that in these cases the input should be validated, I think that 
was the original topic of the thread.  But I don't think you can call 
this "rare" as a general rule.
