Indeed, that could be bad. Even articles not on the main page should be static, IMHO; that way it takes at least two clicks (which usually indicates a determined user) to get to possibly mis-rated material. If you have something more to say than the original post, an addendum in a reply will usually suffice. As for making mistakes in articles, always be sure to use the Preview button before submitting.

I don't agree, I want all nodes I've written to be editable
by me. Most nodes are editible now and I don't see any
major abuses. What I usually see is this, when someone
one of their nodes and doing that makes a following node
meaningless, then the person who editied their node adds a
note to that effect.
I don't see why the articles on the main page aren't
editible, it seems to me that it wouldn't be abused any
more than the current editing feature is.
Adding further addenda (addendums ?) just adds clutter where
editing the original would have sufficed. IMO.
As for using the preview, well this node doesn't seem to
Baldrick, you wouldn't see a subtle plan if it painted
itself purple and danced naked on top of a harpsichord,
singing "Subtle plans are here again!"
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.
