I'm a hearing developer with conversational ASL skills, and there was a brief time when I had the opportunity to work with a Deaf developer. We didn't get to write much code together, but he was able to help me learn the signs to talk tech jargon and we had a grand old time. He was thrilled to be able to communicate effectively with someone at the workplace. One of the best parts was seeing my coworkers react when I started signing with him - I hadn't mentioned that I could use ASL.

ASL is a pretty easy language to learn and it's pretty rewarding. I suggest more devs try it, especially if you have the chance to work with someone who you could communicate more effectively with via ASL.
