What perfect of things you write remain unpublished? i.e. documents, blog drafts, tweets, board posts you deleted, etc.

Curious whether people are more inclined to post unfinished stuff onto the web rather than leave it dormant. I was just looking at how much half-written stuff I have in my Google docs and was a bit confused why I haven't done something else with some of it. Even if it's just a case of re-purposing it.
