re: other stuff
Site clean, main image clearly shows what you do in 0.5 seconds
maybe more 'meat' on the right side you integrate with, even if its 'beta','coming soon','planned Q3' etc (remember - the time saving value your product adds goes up with the number of sites a customer needs to manage.. integrate more = more savings)
Newsletter/want to stay updated on our progress? (ask for my email address on page 1)
site metrics, where are folks clicking, where do you lose them? (checkout crazyegg)
conversion? email campaigns?
blogging & guest posting? - need more than one! even if its weekly release stats (my favorite is http://blog.foreflight.com/ as they mix news with tutorials and 'did you know's)
Any case-studies / testimonials?
screenshot to show ease or walkthrough to show time savings? (screenflow software)
best of luck!
