There is another phenomena that appears related to this. Younger americans are adopting an interrogative tone for sentences that are supposed to be statements.

The salmon was really good? I really noticed this in my German class. There are students from various countries, and one of the students was an American girl in her early 20s. She was a nice person, but you could really see people going through the "are you telling me or asking?" confusion all the time. I think there's something deeper going on here. I don't want to wax philosophical too much, but our current culture appears suspicious of statements. As if uttering them is crass in some way. I don't claim to understand why.
