This is really unfortunate and takes away from HN. I'm fully in favor of defaulting to maintaining the original title but often it's so vague to be completely meaningless. Most people don't have time to click on every link so we simply pass on content that we would have read with a descriptive title. Generally I just pass the first time and check it out if it's still on the front page later; thinking it might be worthwhile if it's popular enough to still be there.

Of course, in this case, it is a descriptive title for the talk but completely takes away the specific thing the submission is about. This is slightly less bad but still bad.
