Reddit is a heterogeneous collection of wildly different subreddits. Some subreddits (/r/pics, /r/funny, /r/WTF) are "average" as you described, but others have different demographics.
For example, I would hardly call the typical user of /r/TalesFromYourServer to be a 20-25 year old male STEM-educated nerd.
I'm going to guess that this was not posted in /r/TalesFromYourServer. The mere fact that it attracted so many comments means that it was posted on one of the "average" reddits.
It was posted on /r/nyc. Which isn't a default sub-reddit, but would probably still be subscribed by "average" users.
Until I checked the subreddit, I assumed "server" meant a beat up old PC running some obscure Linux distro in a corner of some basement, and I was about to call you out... :)
