One of my blog readers, John, is vision impaired and reads blogs with the use of adaptive technologies.He's wanting some advice on identifying online resources to assist him in finding a position in clerical work or customer service. John posts his questions here.

I figured that there are enough experienced bloggers and recruiters that read my blog to help John with some ideas:

Aside from Technorati, where can John go to locate blogs and or discussions relevant to his career pursuit (clerical/customer service) and telecommuting?

What blogging tools work well with adaptive technologies?
