The "old" internet still exists and is alive and well on what I'll call "single issue" web based forums. Photo.net is still here, as are similar groups for cars, bikes, and rabbit holes I have yet to break my ankle in.

Unlike social media, few of these forums have mechanisms to "like" or upvote posts so there is no reward for posting just to attract attention, whether it be positive or negative. That changes the dynamic IMHO. People post to seek answers to their questions, or to share their knowledge and answer other people's questions. This is the way.

I'd include HN in this group of ye olde internet forums. It does have a mechanism to vote, but it's different and the expectation of the readers are brutal to frivolous posts (of which I have made only couple and paid for dearly).
