The intentions are good, but right now it looks like an incoming traffic source (and since it's on HN's front page, it might have succeeded).
It enumerates the Top 10 Most Critical Security Risks, but doesn't explain what each one really means, gives examples of where and how they're exposed, or how to mitigate them. Things that OWASP does.
Now, you might say that it's just the beginning and they iterate. Fine, but without any detail on these Top 10, this document is not super useful.
It would have been better to wait until it had more "meat".
