    Below is a copy of a message I posted several years ago to the memetics list
    that clearly indicates that I do not in any way suggest that team sizes
    translate directly into propagation rates or prevalences. It's not a point I
    wish to argue all over again.

    It takes two teams to play the game, even on Enron Field.

    A reasonable question, Tim.

    The answer is that we cannot just compute conversion rates on an a priori
    basis, even in cases were it is very tempting to do so. Peer to peer,
    parent to child, and other modes of transmission still have to be measured.
    If we introduce a new sport requiring 18 players per team, we might very
    well find fewer conversions than a closely related sport with 9 players per
    team. The idea of taking on the bigger task of recruiting 18 players may
    deter people from even trying.

    In the case of baseball and baseball, there is also the matter of
    seasonality. With both indoor and outdoor courts available, recruitment for
    basketball continues during the winter while amateur baseball recruitment
    fades drastically. Evolutionarily, the climatological environment has a
    different impact on the two sports. The increased after-hours availability
    of school and health club basketball courts in the US also favors an
    increased recruitment rate for basketball during the winter.

    As Bill points out, the mass media and famous players play an increased
    role in recent decades, too.
