I don't think Wave as a product failed. I think it failed as a product Google imagined/wanted it to be. They expected Wave to replace the way we use email. I didn't buy it then and I don't buy it now, after the fact. The tech was cool and useful but changing consumers habits and especially on something like communication is very very hard. So I am not really surprised it did not get adoption. I agree with some of the comments below that if it was integrated tightly within Gmail, it would worked better and PERHAPS it would helped more users try it, like it and adopt it ..slowly.
