The Beckett basketball card forum is notoriously quiet.
On other message boards (which I won't name because I know my post will be deleted/edited), baseball and American football are still more popular than basketball, but by less of a margin.
Meanwhile, although there might be more baseball and football collectors, many of the basketball card collectors have the deepest pockets and it has perhaps the widest global appeal with many collectors in Europe (such as myself), Asia and Australasia.
