Tempus fugit, and all that. :)
But if I was starting the comic now, using the same "decade ago" time period would put Tiffany in the position of being nostalgic for 2002-2003, i.e., the post-9/11 dot-bomb era-- something I'd be hard-pressed to find much to be nostalgic about! ;)
But Tiffany's '80s nostalgia wasn't just "I liked that time 'cos I was in school," it was also pretty central to her whole character. The very idea of being a rising star/supermodel wannabe is a very "1980s" sort of idea. I can just see it being the subject of a light comedy flick starring Kim Cattrall and, I dunno, Steve Gutenberg or someone like that. Like Tiffany's family backstory (her mother's Cold War escape to the U.S., her father's spy thriller lifestyle), Tiffany herself and her hopes and dreams are a product of their time.
I think that as much as anything was one of the things that led me to the decision to bring SJ to a close. It was of an era, and when the era was done, so was the story. What's been tripping me up since then is finding a new story to tell. I'm getting there, tho. :)
