Moses (nnythm) and I browse Hacker News daily. Show HN posts are some of our favorite parts of HN. We wanted to create a way to browse Show HN articles, even those that might not quite make it to the front page. We created http://www.hnshowcase.com last weekend to make discovering projects posted on HN easier. It searches all "Show HN" posts and generates a thumbnail view for each of them. You can sort by submission date, points, and number of comments, and navigate with left/right or j/k keys.
We used the following technologies:
HN Search API, Pyramid web framework, jQuery, url2png and thumbalizr for thumbnail generation, and dotCloud for hosting.
Let us know what you think and how we can improve the user experience!
