This topic seems to always come up, but I have a fairly strong opinion about it, so I want to write a little blurb.
It's true, the Hearing world seems to make very little effort to provide D/HoH with quality captions. So why in the world should we caption ASL vlogs? If the Hearing want access, let them learn ASL, right??? Here are the reasons I think we should at least attempt to caption our ASL vlogs:
1. Lots of HoH and late-deaf don't know ASL, or are learning but are not fluent enough to follow along. I am HoH/late-deaf and I definitely have an interest in keeping up with the issues. I've been learning ASL for 4 years now and quality captioned vlogs like Seek Geo have helped me enormously to learn more common ASL.
2. Hearing people that have a vested interest in the issues may not know ASL at all. Think about family members, teachers and medical professionals involved with D/HoH kids. We should certainly want to help educate them about the issues, since that is in our best interests as a group. But if they visit a vlog and it's not captioned, then we just lost that opportunity. Who knows, maybe a captioned vlog will spark an interest not only in the issue, but also learning ASL!!
3. Captioning vlogs can help Deaf improve their English. This is always a good thing, right? A Deaf friend of mine pointed out this benefit to me a while back, and I think it's great.
