Neologism for a neologistic age: "Minimum viable user"

In my recent comments on Google Chrome, I tossed out a phrase describing the lowest-skilled user a product might feasibly accommodate, or if you're business-minded, /profitably/ accommodate. The hazard being that such an MVU then /drags down/ the experience for others, and in particular expert or experienced users. More to follow.

First, this appears a new coinage:

For information systems -- say, webpages -- the accomodations which are most useful for perceptually-challenged users are /also/ almost always beneficial to others: clear, high-contrast layouts. Lack of distracting screen elements. A highly semantic structure makes work easier for both screen-readers (text-to-speech) /and/ automated parsing or classification of content. Clear typography doesn't fix all copy, but it makes bad copy all the more apparent. Again, positive externalities.
