This is my first ever Angular JS project, and I built it while I was studying some basic concepts. I used all the standard AngularJS associates, such as MongoDB and Meteor.
I also implemented a login system using Angular's OAuthentication technology. Incredibly easy to implement and I got a bit stuck when I wanted to pull data from social media into my DB. It was just a more complex process that I was willing to get into, so I put it to the side for the time being. Also, since Angular is relatively new, documentation was not always that easy to access.
Also, this project is open to evolution. I plan on really incrementing the amount of input from users and create a good data visualization interface as I go along.
