1. Make native android development easy. Why can't I develop android apps in language of my choice - python? I don't like java. If you can let me easily develop cross-platform native mobile app it will be a bonus.

2. I need a HN recommendation system that uses machine learning algorithms to learn about my likes/dislikes(upvotes), find other users who have similar likes and show me a custom list of posts based on that.

3. Use HN Search API to find all articles/comments submitted on HN for a particular search keyword (e.g., "machine learning") and present it to me in a way that let me easily browse the information and sort it on basis of points, date, relevance etc. In short, if I need to find learning materials on HN for a given subject, I should be able to do that.

4. Develop a complete REST API for HN. I don't know any way other than scrapping to do it.
