Yeah what if there was another site that was a bit more exclusive and promoted good faith discussion, maybe related to tech to begin with.. Hey wait a second!
For me HN is more similar to one moderated sub on a reddit, not a reddit as whole.
You can find small moderated communities on a reddit where you can discuss any topics without "noise". Also you can find big popular communities similar in style to 4chan.
And honestly I see nothing wrong with it.
I really hope this site doesn't become the next reddit. I don't think a massive influx of new users would be healthy for good faith discussion here.
But imagine if there would be multiple topics, instead of a single bucket, that - beside some tech news and releases - defaults to the same old discussions.
It would just be reddit (and reddit still has repetitive discussions)
Sarcasm aside, this site actively resists becoming Reddit in many respects. It's in no way a replacement.
