Swing and ska are representations of the American psyche. Most of the music heard at Eugene's small all-ages club or big bar is hard rock or grunge. Swing is very different rhythmically. It has a lot more interesting harmonies. People don't dance together now, they haven't done that for years.
Swing is now less male, less hormonal.
Women aren't bowled over by men in the audience anymore. The danger is when you have a streamlined, stylized movement. You begin to fall into cliches. So, I'd like to see people consciously bring other influences in, like salsa. It can only improve the music.
