I looked back through archive.org a few years ago to anecdotally prove this theory to myself and yes, on the front page the factual content (in my personal opinion) as opposed to meme content seems to drop between 20-40% compared to more recently.
The same seemed to happened to digg.com which made people move to reddit (remember that before it killed its user base?). I really hope this never happens to Hacker News...
That said: Mass appeal always lowers the quality of discourse, due (in part) to there being more of a bias towards being first (the first comment to make a certain type of joke will be rewarded most) and also due to the fact that people tend to aggregate around things that are fun, not necessarily correct.
btw: IQ is a measure of pattern matching and is used in children to determine mental development relative to their biological age, it shouldn’t have any affect on internet discourse.
I don't hold a bias (I couldn't if I wanted to - I have a son with Down Syndrome) I just wanted to point out a reason for the change - which you more eloquently wrote - since I miss the more technical discourse.
On Reddit, the serious subreddits don’t have a lot of memes and many prevent them. On Facebook if your feed is full of toxicity and politics, it’s because your friends are FB warriors and toxic.
Yeah, you really demonstrate how it's lowered. Intelligence quotient quotient
If you take a small pool individuals who discuss technical topics, and dilute it with more people it will trend down owing to the population IQ approaching the average of ~100.
Technical articles will also be less prevalent owing to the relative greater number of non technical topics and less interest in those that are.
It's not that technical people don't enjoy memes, it's that the wider populous won't enjoy esoteric technical or scientific articles.
