Check out this article by Howard Bryant of ESPN.com. It talks both about the significance of the Giants win, and also how MLB may be changed by this year's World Series in the form of another Wild Card team, etc.
It's some good reading while we wait for some more significant Hot Stove stuff to develop.
PS: Thanks to everyone who watched my World Series video. If you still haven't seen it for some ungodly reason, get on it. For God's sake, it was talked about on Murph & Mac on KNBR.
