According to this article, some people "live blog" the birth of their children. Or a funeral they attended. Or an afternoon spent cleaning out a closet. This means banging out blog posts as the events are happening.
I post to this site pretty often, sure. But I would never "live blog."
If people feel the need, they can blog the shit out of my funeral for all I care. But I hope they will have the decency to post their content later.
