Not me but I was pleased to hear David Granovsky's comment in his blog "The Stem Cell Blog" when he covered the Chloe Sohl's story on her miraculous recovery from her hearing loss using her own adult stem cells. David went onto say that basically he forgot about people with hearing loss may unable to hear or understand fully what the original YouTube version of Chloe's story. And that he was "blinded" by his own hearing for not thinking about a captioned version of Chloe's video story.
