"Create a free box now!" and "Sign-up for free now!" should be "Find out how we can dramatically improve your development workflow" or some such (better copy).

The currect text assumes that you know what the service is.

Admittedly, I missed the "home" button in the top right as I assumed the logo would take me to the home page, not to the blog. I stopped trying after that.

This is a common thread on HN with launch announcements. I'm not sure why everyone avoids the blog pre-amble for posts destined for link aggregators:

"Nitrous.IO, the groundbreaking developer toolset that enables fast provisioning and web-based coding and collaboration is pleased to announce the first public beta. To find out more, check out our quick introduction..."

Then move on to specifics. I'm not a copy-editor, but a leading sentence like this would go along way to help.
