Some of my LJ friends put up poems or short stories that they're still working on, under lock. Sometimes they are actively seeking input or help with a particular problem, sometimes they're just sharing it at that stage. Of the things I've then seen published, some have changed a lot and some just a little.

Among people you've come to know, even if only electronically, it seems like just sharing work with friends. I guess sartorias has done it too--put some things up in draft form and then polished them for publication.

I sometimes put stuff up, but I'm considering it more or less done when I do.
