True, personally I'd love it if there was a rebirth, but yeah, loads of things would ruin it, especially given "music" nowadays (Rebecca Black being one of many "musically gifted" people not)
Eh, it has some moments (I seriously will say that The Toasters from America are classed as Ska Punk, but are more 2 Tone in nature, though 2 Tone is the start of ska punk technically, so...)
Dunno, ska's been on and off over the years (50's and 60's original, 70's and 80's 2 Tone, 90's had more ska punk in America), it's kinda unpredictable.
Just seems right, as some fact behind it seems true, as people eventually lose contact with some. I know that I certainly have with people on here, as do others.
