Well done! Incredibly intuitive. The image add/text alignment is great and html editing to boot. Can you tell if many users have added google analytics?
Though simple in-house page view stats would probably work better for 99% of your target audience than having to sign up for GA.
(perhaps there's a business opportunity, do a deal with someone like getclicky.com - have a simple signup/installation of their tracking code in exchange for a revenue share...)
