Learned In Public
One of my fellow CodeNewbies (Matt C) convinced me to join Kaggle's 30 Days of Machine Learning (ML). I just submitted the first assignment, and it's pretty cool.

To be honest, I hadn't planned on getting into ML, but after completing the first exercise, it might be right up my alley.

I am now a Contributor on Kaggle (up from Novice). 🎉
