Time probably, but one can always choose not to post, or to be draftier.

That's pretty much it. I suppose it depends on the type of content you're publishing: openly controversial articles may yield all kinds of trouble, but technical, "cold" stuff, I'm not sure what kind of major issues it could cause.

And also on your intents: if you're publishing to help you think things through, you're essentially never losing anything, not even time. It's just "work."
