No, I don't live near DC, but in the Boston area -- not among what Flip calls "deaf freaks living out in the wild" (?!) Most people that I encounter, deaf and hearing alike, are pretty well-informed in general, just not familiar with how CIs work and what they can and can't provide. In fact, some people with older CIs themselves are unfamiliar with the newer tech.
My point was that I would not be angry or frustrated with people for not knowing how CIs work or expect that they ought to know more, and would be happy to share what I know and what we experience, both good and bad.
These are not stupid or backwards people as you seem to suggest, they just may have not had hands-on training with a CI or learned specifically how they work. Most people haven't. My pediatrician had heard of CIs, but knew very little beyond knowing that they existed. It isn't that doctor's specialty, and the dr. didn't pretend to know anything about CIs, had a ton of questions for us. I've encountered teachers of the deaf who were shocked that students could hear whispers or talking from outside the room, hadn't realized how distracting all that sound input could be, and another who was broadcasting really loudly using the FM system in a way that works great with her kids using HAs and needed extra high volume, but was distorting sound for those with CIs. I wouldn't expect someone who doesn't have a CI or a child with a CI or who hasn't been formally trained in CIs to know a great deal about them, just as I don't expect the average person to know the ins and outs of a hip replacement or a pacemaker.
About 2 years ago, when a relatively large group of children with CIs were enrolled at my daughter's ASL-based school for the deaf, the school's administration felt the need to bring in experts on CIs to educate the staff -- because although they were far more informed than the average person, and all had some contact with CIs of course, they found that the staff really didn't know much about how they worked and were operating under some outdated and inaccurate info about CIs. The staff is about 45% deaf, but that doesn't mean either those who were deaf or hearing knew a whole lot about CIs -- the school's medical staff included. In fact, most didn't. Everyone learned a great deal and shared some great questions and insight. They intend to do these sessions regularly.
