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. By doing this, you would be forcing the Twitter recommendation system to work for you.
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.
