Ask HN: Where/How can I find trending CS research papers?

I've been very interested in this as well.

A good place to start is at -> http://arxiv.org/list/cs/new If you want a specific area of CS, then on the home page -> http://arxiv.org/ you can scroll down to the CS area and find specific CS topics.

For instance,

* AI -> http://arxiv.org/list/cs.AI/recent

* Computer Vision and Pattern Recognition -> http://arxiv.org/list/cs.CV/recent

* HCI -> http://arxiv.org/list/cs.HC/recent

* Information Retrieval -> http://arxiv.org/list/cs.IR/recent
