Social media platforms, particularly Twitter, help you to stay updated in the field. There are many people you can follow. If you are unsure of where to start, I would recommend following Jeremy Howard (https://twitter.com/jeremyphoward), and any interesting people he may follow.

Another important Twitter account you need to follow is PyTorch's (https://twitter.com/PyTorch). The amazing people behind PyTorch have some great content being shared.
If you are looking for research papers, then look at arxiv-sanity (http://www.arxiv-sanity.com/), where many smart researchers publish their papers.
More great resources for learning about PyTorch are its tutorials (http://pytorch.org/tutorials/), its source code (https://github.com/pytorch/pytorch), and its documentation...
