I am just working on my sport prosumers abstract for NASSM, and I realized that the The Blacktop at the Global Village is a good example of prosumerism. If the powers-that-be ever get around to doing this, I will damn straight be down there for my thirty minutes of run — regardless of how brutal my 'jumper' is at that point. And I'll be contributing to a sport infrastructure that will provide for my kids, my grandkids, and so forth.
Hey, sportocracy! If you want there to be another golden era in professional sport, you will engage more people as prosumers — as participants in the process — rather than depending on consumers/spectators. Oh, and it wouldn't hurt if a bunch of those people were participating as athletes.
