Ask HN: How do you keep up to date with your field?

We are reading blogs less often [1], and most of us here are in fields that are rapidly changing. What works for you in keeping up to date?

The answer for me has been learning a little bit from hacker news, a little bit from coworkers, a little bit from meetups, and a few good aggregations of the best posts in marketing, entrepreneurship, js, etc. But, it feels like there has to be better ways to do it.

I am curious to hear good ideas.
