I wont stop indexing no-reply/no-answer questions, regardless of G (only a very small percent, as always with Q&A).
I'm clinging to what googleguy/cutts said back in the day about 'quality' winning out over everything.
No reply / no answer question pages being indexed are not going to pass the quality sniff test. (If I were a user and landed on one, I would be pretty steamed)
