@perloid @clacke @liaizon I mostly agree. However, there are plenty of times where I think the mistake is better.
In the end, language will change even to embrace mistakes. As I age and work more and more with people from all over the world speaking many different native languages, I roll with the paunches :) and try to accept the spirit rather than letter of the thing being said. Sometimes the mistakes do matter and I have to get clarification. I will make corrections if a safe means presents.
