Ask HN: Please review my Rails API for Hackful Europe

Hi guys!

My name is Oemer and I'm a Software Engineer from Cologne, Germany. I'm pretty silent guy around here but in the last couple of weeks I took the chance and developed an API for hackful.com (HN like site for european based startups).

To implement the API I forked the project on GitHub and you can see it here: [https://github.com/Oemera/hackful](https://github.com/Oemera/hackful)

I want use this API to create an iOS App and make it also open source :)

What do you think about the API and my Rails code?
