The distribution of positive "anymore" is only vaguely geographic; mostly it's social dialects -- speech groups not necessarily distinguished by location -- that show it.This is true, for the most part, but I think there are nevertheless geographic limits, outside of which no one of any social group uses positive 'anymore'. The problem is, I don't really know where these limits are. Astute commenter and aspiring professional dialectologist Corrine/Queenie recently joked that the boundary ran through Chicago's western suburbs. Though she was joking, this may in fact be the case.
A while back I wrote about American words for 'soft drink', and I included a beautiful map based entirely on responses from an online survey. So this got me thinking: why can't I do the same thing for positive 'anymore'?
Here's where you come in. Tell me two things: 1) if you find the sentence "Gas sure is expensive anymore" shocking, or would have found it shocking at some point (not whether you've heard such sentences or if you use them) and 2) the zip code where you spent the biggest chunk of the first ten years of your life. Then bug your friends to do the same. I expect that in a few years I'll have enough thoroughly unscientific data to make an equally unscientific map. Maybe then I'll be able to sleep at night.
I don't use positive 'anymore' natively. At least I don't think I do. I think that anymore I use it as an affectation of sorts, or as marked speech. But just because it isn't part of my dialect doesn't mean I can't love it.
