I know that google docs is accessible if you turn screen reader mode on, which I think happens automatically if a screen reader is running. Windows has a flag which gets set when one is running, and sites can pick up on that using ARIA. The only thing that is annoying about it is that it speaks every character you type irrespective of your screen readers settings. I can't deal with that, it slows me down in typing and bugs the crap out of me, but if you like typing echo, then sure, go for it.
