Inspired by the thread voting does update, I have made a change -- experimental at this point -- to test the viability and desirability of separating the edit your post capability out of the normal threaded view; the vote on posts capability would remain in the normal threaded view as it is.

To check it out, find and view a root post of yours in the Obfu section. (You can find a list (if you have any) here.) Currently this change is only in effect for that specific scenario: root Obfu posts.
You'll see two differences:

1. The textarea labeled "Your obfuscated code", where you could edit the content, is gone;
2. There is now an "Edit" link above your post, on the far right side.

If you click on that 'Edit' link, you'll be taken to a page which, like original post/preview pages, allows you to edit your post but does not show you the rest of the thread, nor to vote on posts in the thread.

Note: janitors (and other authorized members) will see this 'Edit' link on any post* to which they have edit permissions, not just ones they own.

* Currently only Obfu root posts, as I said above.

I think this change, if adopted across the board, would have the desirable side-effect of suppressing, however slightly, the tendency of monks to edit their posts later. What are your thoughts?
