I find Twitter helpful when I'm covering games, especially because I'm usually doing high school games. For instance if I'm covering a hockey game I'll tweet out goals and other, what I think are, salient observations. Also, I find it really helpful when I'm writing on deadline to be able to go back through my tweets and find something I forgot. Especially with flowing games like soccer, basketball, or hockey I find it really helpful to be able to look back and see "Jenkins out after Sanderson hit and Podunk doesn't look the same." IT jogs the memory and adds a layer to the story.
