why?

not blogging.
I have enjoyed it so.
I saw someone's blog with a bunch of personal stuff that
felt boundaryless to me.
I know, I know, the web is supposed to be a spider's web
connecting all of us all of the time...
but,
aren't thoughts censored before we write?
When we post to blogs, are we doing it to sell a product?
Or, to develop a public persona for other reasons?
Is it just a journal - I don't think so when others can read
it or use our images???
