Show HN: Platform for data scientists

I've started a side project http://datasourcehub.com which aims to be a platform for data scientists. The project is still in the idea phase so the UI/UX and functionality are all subject to change. Feel free to play around, below is a guest login, and make sure files are content type of 'text/csv'. All data is subject to deletion, it's just a sandbox right now!

By reaching out to the Hacker News community I hope to reach expert data scientists and get their feedback. Below are some questions I'd like to answer and some proposed directions that this project can take. Any advice will help!

login: guest_account / password: foobar

Questions:

1. What core feature/s would data scientists like on a platform made for them?

2. How difficult will it be to get people / organizations to contribute data?

3. Who would be good resources to reach out to initially?

Directions?:

1. github for data scientists (shell command wrapped around diff and patch for data files)

2. dribble for data scientists

3. hosting of large datasets (pastebin style)

Please reach out to me here or email me (in profile). I will respond to all feedback. Thanks again!
