One of my hero's and closest friends is deaf -- my younger brother. This is a wonderful article. Honest and sincere. Very cool of your founders to let you post this.
Seeing what life is like from the techie side of the road as a deaf man is a great reminder to work more collaboratively with our colleagues whether they are deaf, or any other cool things that make them unique. e.g. English as a 2nd or 3rd language. etc.
Just recently, I started a new business with a partner. We carry little notebooks around to capture things as we surface them. Sometimes I do a quick audio recording on my phone. The most prescient ideas, questions, problems to solve are transferred to a Wiki he created for us where we can track further dialogue/brainstorming, ownership, and closure.
