These things should come with warnings. Something like:

Warning: If you know the author of this blog, the contents may unsettle you.

Just a polite way of reminding you that if you read these sorts of things, you never know what you might find. Or how it might make you feel.

Friend sends me a link to her blog (not a xanga blog). I read it. I look at her profile. I look at people she has linked to. "Oh, I didn't know X had a blog..."

Click.

Oh.

There is no Unclick.
