Considering almost every human I know uses Reddit in some capacity (technical and non-technical), that's pretty likely.

You're in a really self-selecting crowd then. Less than half the people I know use it, mostly because my social group is outside of the tech world.

Reddit is in the top 10 most popular websites according to Alexa. I'd venture to say most reddit users aren't people in the tech world.

I know exactly one person who uses it. To me it always seemed like 4chan-light.

There's a difference between people who come across or read Reddit, and those who actually post and participate on Reddit. The Average Joe is usually part of the former.

Perhaps not all tech, but my point is that it's very unused by many. People in tech are far more common users.
