really? Isn't the name "southcore" kind of forced?
When the media starts to use it, people gradually get use to it. Better than saying "Yonge and Eglinton" IMO, which always reminds people of a specific intersection that the identity of a nabe. Only neighbourhoods that are not neighbourhoods are named like that (which is probably true for Y&E).
I live in the Yonge & Eglinton neighborhood and I love it. I think it's the perfect name for this neighbourhood and I like the nickname "Young & Eligible" as well. Just because its named after the major intersection doesn't make it any less of a neighbourhood when I am walking around enjoying it imho. #2cents
