I don't consider myself as a deaf geek or deaf techie but I've had a handful of experience working in the dotcom and IT sector especially in the silicion valley. One of the challenges I believe most of the deaf/hoh techies out there is still the communication barrier. Programmers work in team of 3 to 12 depends on the size of the project, email is a great way for the deaf programmer to communicate with his/her colleagues, but when it comes to the weekly meeting to duscuss project process, interpreters just doesn't work. There lack qualified interpreters understand the programming concept, heck, some of them never heard of PHP!
Another thing I see is that senseless egoism amoung those deaf programmers. They think that their knowledge and from high school and community college programming courses are sufficent for demand of the industry. well guess what, it is not the same. I bet there are only one or two so called "developers, programmers" on this forum know how to code up a server side java program.
just my 2 cents
