I don't know how much truth there is to it since I'm a relative novice at language learning, but from what I understand reading texts is a) excellent for building language skills and b) pretty terrible for your pronunciation and listening comprehension until you have some level of fluency with the language.
That's according to Marvin Brown who pioneered the AUA school for teaching Thai via only comprehensible input. The school seems to have a pretty solid track record of producing (western) graduates who speak without an accent. Pretty interesting stuff. He called his method Automatic Language Growth or ALG and of course there are strong opinions about whether or not it works as well as it is claimed.
