An editor's nightmare

One thing I hate about the fact that everyone now reads blogs in rss readers (or whatever I am supposed to call those) is that when I change things, which invariably I do, the version that people have in their readers stays the same (some readers are better at updating than others it seems). And sometimes I accidentally hit the "publish" button instead of the "save" button when I am writing and post something I haven't even finished yet - and then I scramble to save it back as a draft but realise that it is probably already too late for those (faithful few) of you who have me in a reader. Or worse, when you delete a post altogether (which I just tried to do) it stays there. This is very frustrating! It's the point where you lose control of your own blog! Does anybody out there have a strategy? (Perhaps I just need to sleep on things before I hit the post button in the first place.)
