As a native of the state and about 28 total years of my life, I'm much more open to Wisky (either using the term or hearing it w/o cringing). I tend not to use it though. I do not embrace the use of 'Sconnie' and do not use it for any purpose. It reminds me of the lazy baseball nicknames that are far too common. 'Let's put a 'y'/'ey'/'ie' at the end of his name.' 'Jonesey' 'Brauny', 'Mollie', etc.
Though see it quite a bit when I'm in WI, which is fairly regularly. Alum and non-alum. I do think it skews younger.
