NPR (October 23) reported that 8 in 10 Americans under the age of 30 have read a book in the past year in comparison to about 7 in 10 adults in general, American adults under the caption “America's Facebook generation is *reading strong*.”

I don’t think I’ve head “He / she reads strong,” or “He / she is a strong reader” very often.

OALED shows “strong” as the adjective to mean “great in number” in its 14th definition from the top – 1. having a great power. 

Is “Read strong” a popular way of saying “Read a lot (or hard)”? 
Can I say “listen to strong,”
“Write strong,” or “eat / drink strong,” by the same token?
