I watched Tina's video about accessibility on social networking sites. I guess I have been oblivious because I assumed that applications such as Facebook with 800,000 + members would have either voluntarily or have been legally compelled to ensure that people with disabilities could use their product. In my narrow window of observation, I have seen Facebook and texting open the world up for my neice who is deaf. She used to have to rely on a telephone relay service to communicate with others who weren't in the room with her. Now she can readily communicate online and with texting. Life has opened right up for her. But, there are indeed other disabilities that should be addressed by these companies that are truly pillars in the social networking field.
