The reason I used canned tomatoes in that soup is that there's been scarcely a tomato that I've checked in the farmer's markets which smelled like anything. I'm guessing it's a result of a rather cool, damp summer in and near Philadelphia
I've also guessed without checking that if a tomato doesn't smell like much, it isn't going to taste like much. dcseain tells me that there's actually no correlation between flavor and smell for tomatoes, and I admit that I hadn't considered the possibility. I will say that insisting on tomatoes that smell good is a way of getting tomatoes that taste good.
