Reviewing 2018 and Previewing 2019

Kaggle Kernels is our hosted data science environment. It allows our users to author, execute, and share code written in Python and R. Kaggle Kernels entered 2018 as a data science scratchpad. In 2018, we added key pieces of functionality that make it a powerful environment. This includes the ability to use a GPU backend and collaborate with other users. We had 346K users author kernels in 2018, up 3.1x from 111K in 2017.
