I have been using this plug in for quite sometime. I quite like having the ability to know how many words there are in a post. It’s useful! So I’m now recommending this.

It also has readability scores, but I don’t know how useful they actually are for writing as I actually tend to just write. The readability statistics are quite practical once you know what they signify. I found a website that helps provide some ‘standards’.

This post rates: Fog: 9.6 which indicates that you need 9.6 years of education to read this, or a headcold to write it!

(edited: the two possible modes of writing with ‘tags’ and mini-word style buttons produce widely different numbers of words).
