I see that your account is roughly 4 months old. From https://news.ycombinator.com/newsguidelines.html:
"If your account is less than a year old, please don't submit comments saying that HN is turning into Reddit. It's a common semi-noob illusion, as old as the hills"
I've been on HN for almost 6 years, and I don't think it's gotten quantifiably worse. The tone has changed, but it's hard to say much beyond that. In fact, the moderation has gotten much better; and 'pg not commenting anymore has (in my very subjective opinion) improved things (any of his comments would dominate a thread's discussion).
"visual studio code 1.9" getting the most time (in the front page), upvotes and comments for the day is a prove of this happening.
