I am one of the founders. I do not consider it dwelling on the fact that we were rejected. It doesnt actually bother me at all as you can see from most of my previous posts I have been labeling ourselves that way to help motivate others to keep pushing forward. The second reason i label it this way is because i think on HackerNews people are naturally curious about all the Ycombinator applicants a little bit more than just any startup. I may be wrong though but this is my reasoning for highlighting the fact that we were indeed rejected but continue to move forward.
