This is great! I'm really glad you did this. I have no need for subtitles myself but it's nice to have 'em -- especially if I want to send the episode to someone who doesn't have speakers or would rather not turn the volume up at work! :)
One comment: I think Dr. Chalmers says, "Why would I want some mechanized proxy jabbering at me." But then, Chalmers races through his dialog so fast, it's hard to make out.
Its nice that someone is thinking about the disabled. Everyone should be able to enjoy the Strangerhood. The disabled are always getting the shaft. Have you ever watched a TV show with closed captioning? MAN IT IS SO BAD. Half the time the words are hardly legible. I feel bad because of all the spelling mistakes. I mean for me a person of hearing, i know what they are saying because I can hear them but the poor deaf people. Good job!
