Are you the author? If you add 'Show HN' to the title the submission will go to https://news.ycombinator.com/show requiring less upvotes for exposure. It helps to also add a first comment "I'm the author" with a little background and asking for feedback. I use geojson at work and will try it out.

Hi there, thanks for reaching out! I just submitted it again including 'Show HN'. Thanks for that. I am not directly the author of the application but I am working with him to make it the best GeoJSON editor out there ;-) So any feedback is welcome!
