The argument "Only worry about yourself" doesn't apply to those passionate about flourishing.
It applies everywhere, if you step away from the community and worry about yourself, develop new techniques and moves, then possibly if you feel like sharing your hard work post about it on the forum. You can't successfully advance cardistry all at once, only step by step. There are always those who will get left behind and that is okay; This isn't school. They will catch up eventually, or create the next big thing.
But I like your idea though Creeper I am looking forward to watching your success.
