The NCAA has now instituted special "live-blogging rules" for anyone credentialed to cover NCAA events. The rules change per sport, but they limit how many times you can blog during the course of a game. For baseball: once per inning (not even once per half-inning!). For basketball, it's five times per half, once during half-time, and twice in overtime. Football is three times per quarter and once at half-time. It even covers the more obscure sports: you can only blog 10 times per day at a swimming match, for example. You can see all the details here (pdf).
