A blog post describing this would be more interesting to me than how you e-mailed a TechCrunch author and he wrote an article about you.
I don't mean for this to come across as snarky or belittle your post—it's just that you basically e-mailed a short pitch to a TechCrunch article and got an article out of it. That's not really revolutionary; lots of 'unsexy' (see: Enterprise) startups get covered on TC.
EDIT: Or, comparing the effects of your TC coverage against more targeted 'focused coverage'—since I think a lot of startups fall into the "we need to be techcrunch'd" trap and don't realize how effective other less buzz-worthy but more targeted media can be.
