For sure ... in fact, there was quite a show at Alta last week...I try to avoid these kinds of mistakes because...well...its annoying.
There is one situation where I think they should be completely tolerated and thats when its Siri error. If Siri uses the wrong word or spelling it should be ok to just go with it. Thats the convention used with many of my friends. We all know its a Siri goof and don't waste time correcting it. Its Apple that can't get it's act together not the author.
