If all you wanted was to find out about how companies are using Twitter you could have posted an "Ask HN" asking just that question.
If you want feedback about your startup you can post an "Ask HN" about that, too, but don't go pretending that you weren't just playing for traffic.
Looking at most everything in the new section, they all link to outside links, so I thought that was required - like Digg. I restated the question here AND linked, so I could get responses here without the need for people to follow the link. Extra traffic to Trogger was a bonus, sure, but after SXSW and the hype of Twitter that continues there, I was curious.
Still, I'm not sure what your role at Trogger is, but if you're involved in marketing or promotional stuff you should understand why I and the other people who voted you down reacted the way we did.
Next time act in good faith. Ask the community directly and if you want to post a link to your own startup don't pretend that you "found it" on "some community site." Tell us up front that it's your startup and gosh HN is great and we'd love your feedback, etc.
