An amazing pitch is not an amazing product, and vice versa. Yes a great story is going to get eaten up by bloggers. But that doesn't apply to rule #0 above.
i guess it comes down to this: quality of worth as it pertains to impact in the real world does not directly correlate with quality of worth as it pertains to the value it has as a news story.
i maintain, however, that if your goal is coverage, then by definition "worth" is only relevant to the ability for it to be covered at all.
