Just because you have the option to edit an article, doesn't mean you should. If you want to tweak the message because you learned something new, don't edit an already existing article; WRITE another one. Allow your articles to keep working for you. Remember, the more high-quality live articles you have, the more traffic, exposure and credibility you'll receive - so only edit the articles that REALLY need it. Your time can now be better spent writing great articles and not agonizing over making each one perfect.
