This sort of thing really needs a live demo. I don't want to sign up for 50 different Product Management sites to find the one I want to use, and have to deal with the other 49's spam once I choose one. Even once you delete your account do some of them spam you.
Nice site design. You may want to take a look at a mixed-mode error you have -- there is a call being made to <a href="http://www.prodpad.com/wp-content/plugins/prettify-gc-syntax-highlighter/prettify.css?ver=3.9.1" rel="nofollow">http://www.prodpad.com/wp-content/plugins/prettify-gc-syntax...</a> -- you can probably just change it to https and clear that right up.
