I am currently a PhD student, and as everyone else, I try to keep updated with articles in my area. I was wondering better ways to keep updated, particularly, what technologies could help to do this job quicker.

I have seen for example this question, but I believe my question is more specific.

For example, I set RSS tags on arXiv to be sent to my email with some important key-topics in my area. I also follow questions about it in Mathoverflow, setting email alerts as well. And recently I set Google Scholar to send me emails when some authors on my field either publish new articles or when they are cited by someone else. I like to use researchgate as well, but to be honest, I did not manage to make much with it.

I would appreciate any suggestion for this workflow of getting updated and I apologize if this question is too subjective.
