#0 Build something worthy of coverage.
Now that you understand the blogger's job, you should be able to understand if your pitch is "worthy" to THEM. If it's not, DON'T pitch it, period.
The above might sound simplistic, but after running a marketing firm for four years, I can't tell you how often this advice is unknown, overlooked, or worse, ignored. Your news is "worthy" if it helps a blogger do their job, if not, it's just plain not worthy.
No matter how much you are proud of your accomplishment, if it's not interesting to the readership of an outlet, it's not interesting to the blogger, and that's that.
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.
