I almost always wind up editing my posts after I've posted them. The RSS feed, though, comes from the first draft of the post. So if you've got a feed hooked up to this site, then I recommend you actually click though to the blog entry. That way you'll see the current edition of the post, with any corrections, clarifications or updates. If you don't, you might be missing something.
Of course it's your own trip, so be my guest, but please be aware that there is a warning on that one.
