When you first log into Blogspot, there is now a video tutorial that pops up. I had contacted them before about the video not being captioned, but I don't think they read the "feedback" blocks they provided. The video is still not captioned.
I suspect Google will be hearing from a lot of deaf and hard of hearing people about the video tutorial without captions. At least, I hope so. If you depend on captions, hop over there and let them know about it.
