I honestly dunno about this.. its a mixed blessing being deaf in the computer industry.
I consider myself a newbie towards computers, even though most people consider me a guru. With computers, there is ALWAYs something new to learn, even if you are knowledgeable already. Theres plenty of new thing popping up everyday.
Thus, the sole judgement on computer professionals is most often their skill. Period. Any company that favors other factors over pure skill is probably not a place you would want to work at anyway. :P
If you are skilled already, companies and people will look first at that skill, and ignore any disablities.
Negative is that there are lots of ways that you still need to interact with others, and companies are wising up to the fact that a complete antisocial geek is actually counter-productive in larger projects. Thus, some companies might just reject deafies out of a precieved view that we can't be team players. (lots of dumb companies out there).
Of course, anything is a blessing if you spin it right. I've talked to companies that have made audio visualizations, webcams, etc and they have bluntly stated that my perspectives as a deaf person were extremely helpful towards improving their products. Its a matter of providing a different perspective.
