Spontanious articles are often the best ones. When you reread them afterwards, there's always the thought that some things could have been better. But if you start re-writing, you risk overthinking it, and then it becomes a post written from the head instead of from the heart.

In my own posts, I can see big difference between the ones I wrote from the heart an posted without editing it, and the ones I wrote and changed and edited. They simply use a lot of the charm.
And if you feel like you could have explained things better you can always write a follow-up.post in which you do so :0)
