Actually, I think the idea of "published" on the web means it is for an audience.
I can only speak for myself, but I put a lot of stuff up there which is simply like talking or painting or jamming at an open window to me: anyone is free to stop by and watch and/or comment, but I always feel free to be as personal, or incomprehensible, or random as I want to be. I don't get paid to provide a certain service in my personal space, I don't even have to explain myself to anyone; so you know what, I don't. And if someone else posted it to another site, that's something else entirely.
