in reply to RE (3) athomason: Edit original article
in thread Edit original article

Previews are (usually) present on non-editable node submit forms, to allow you to make sure you're going to post what you expect. Since you can edit a reply, the preview button becomes somewhat redundant. Though I'd like to see it anyway; the submit format in general needs to become much more standardized.
