Halley has an interesting post up about why people blog.

The life and death bloggers aren't writing casually. They are writing for their lives. They are writing to stay alive. They are writing about what it feels like to be alive -- knowing that all that will be left behind is their words. They are writing because it really, really matters . Tony Perkins is not Anne Frank -- nor does he want to be, nor should he aspire to be. But like Tony, anyone who wants to join the party needs to be aware of the tradition of this medium --- enter this inner sanctum with head bowed, hat in hand. Tread lightly in this place. Show us your real self. We're naked here, are you? We're alive here, but we're also dying. Dying to tell you our stories. [Halley's Comment]

I definitely can identify with some of this. I don't write about my health issues often (because I hate to seem like I'm whining), but I do when it is important to me. For me blogging is partly about just getting stuff out of my head. And in some cases that's talking about how hard it was to breath on a certain day when the air quality sucked (others it might be why I'm annoyed with cheese). It's as much for me as for my friends who pop over here to see how I'm doing.

And yes, when I get the call to go in for a new lung you will all hear about it here.
