I’m pretty sure the way people in my field (physics) do this is by reading deeply enough that they

A) recognize the names of authors that do good work B) Develop intuition about which results are probably BS and which results are likely to last.

They end up seeing notifications for most new pre-prints, but have built up good enough filtering heuristics that skimming through the paper can inform them whether to read more closely or pass.

If you want to keep up with very recent papers, citations aren’t likely to be much help. You’ll be 6 - 12 months behind if you’re not reading pre-prints (in Physics, at least).
