If he is born deaf or deaf at a very young age, writing a spoken language is like writing a second language to him. Most born deaf people write at fifth grade level or lower. That's probably the reason why he told you he is deaf in the beginning of his post.
Makes sense. I would have been more sensitive if he stated Excuse my writing skills because I am deaf. I was laughing at the way he felt certain things were going to happen because he said so.
I am very comfortable and know that Warner Bros will drop HD DVD, no doubt about it
