I learn a lot. I'm the one management goes to when people ask to use a new tool or process. 95% of the time I have already heard about it and have a basic understanding of it due to HN. I describe what it is, how it relates to other stuff we already use and if it has merit to try out. I look super smart when I can answer on the spot. HN is a good filter to focus me on tools and processes that people might actually use or want to use.
