Learned a new phrase, “situationally blind”, which seems to be Richard Chassell term for:

people, such as car drivers, who should not be looking at your blog [or reading email] while driving – Single Input — Multiple Outputs (via)

At first I thought it might be a common term that I had never heard before, but a quick Google search shows its in exclusively by projects like Emacspeak, and textinfo, which confirms for me Chassell’s coinage. Its a useful term.
