If you are not familiar with Jane Hamsher, she is a film producer who started Fire Dog Lake as an individual blog. According to the Wikipedia article about her, it is named for Hamsher's favorite activity at the time it was started, sitting by the fire with her dog while watching Lakers' games. That's such a great story, if it is not true (and I have no reason to believe it is not) it certainly should be!
