We've all been there. You're about to add a comment to some kind of online forum. Just as you hit the "Submit" button, you realize you've got an embarrassing typo in your post. But it's too late. The forum has no means for you to edit your post and your mistake will live forever in Internet history with your name pasted to it. If only they had a "preview my post" function
Fortunately today's blogging tools make adding your stuff to the global dialog a lot easier, and far less error-prone. One of the nice features of most blog tools is the preview feature. This feature lets you see what your literary masterpiece will look like after you hit the "Submit" button, giving you plenty of time to make sure your post looks exactly the way you want it.
No more missed typos. No more broken links. No more dead images.
