When you're first getting started in tech I think HN seems much more serious than it is.
Once you're a bit more experienced you realize it's a bunch of hipsters talking about simple and insignificant technologies, and completely ignoring everything else as "old".
That being said, I think it's highly entertaining.
> hipsters talking about simple and insignificant technologies
Are you telling me that a new CSS framework that will save you two lines in your CSS files is insignificant? Or a new <insert the current language that is hip>-style language in <insert a number between 1 and 100> lines of JS!
Surely these are the greatest inventions of our time.
I have been active in high tech for many moons and like to look at this place as just another alternative feed for a old man ;) I would much rather HN than other sources, but my time is limited like many. So I just hop on occassionally and learn (or teach) something new. Once in a while a post resonates with me, but when it doesn't that doesn't mean it's just noise. It can mean I have much to learn.
I haven't been on for that long, but I am starting to see examples of what you mean. I tend to weed out what doesn't apply to me which I think many do.
