Yep, this is what I do, except that security papers don't make it to arXiv so I also keep an eye on twitter (I have followed a bunch of academic security people) and a couple subreddits (/r/ReverseEngineering, /r/REMath, and /r/systems). It's not ideal, but it works out okay.
None of them are a substitute for a proper related work search when I'm writing up a paper though, this is just to keep current on what the trends and interests of the community are.
