Disabled computer users often regard their browsers as a lifeline to the world.  But during last year's natural disasters, it became very clear that the lifeline was tenuous - perhaps broken entirely - as so many relief sites were not accessible to those who need them most.  To help people with disabilities find what they need more easily, Google Labs released a new product yesterday.  Called Accessible Search, it optimizes pages based on some key accessibility features, including alt text, keyboard navigation, simple language and so forth.  The idea is to save blind users the wasted time and frustration of trying to get information from inaccessible sites.
