I've got good friends who never went to Withdean, never even would've considered it. They've got season tickets at the Amex and still claim to support United/Arsenal/Spurs.. They only go because of the success the club has been having recently. If we were to go back to struggling at the bottom of League One they wouldn't keep going.
I'm not really too fussed I just agree with the statement in the thread.
Surely we'll only find out just how many regulars are part of this group if and when relegation happens. There's a good chance that many new fans will remain fans if theings go tits up in a couple of years. Obviously not all of them, but I doubt we'll ever see crowds under 10k at the Amex for a league game.
