New Comment Styling

So I've been a little disappointed with the quantity of new interesting comments (since the site refresh) and have partly attributed this to old formatting. In an attempt to sort this, I have created a new visual style for each manuals 'comments'; for those using a compliant and modern browser (FF, Chrome, Safari) you might even notice the cool rounded comment bubbles.

Some people may have also noticed the homepages styling changing between visits, don't panic I'm just running a couple of A/B tests using Google Website Optimiser, more will follow :)

Please feel free to leave comments, if nothing else, I'll have something to read!

P.S. There have also been more speed improvements!
