This is certainly true.

However, consider that the 99% who don't contribute on Reddit, may be contributing elsewhere.

I never post on Reddit, only browse. But I comment here.

Maybe that's the case with most people. That the majority contribute somewhere, but just not all in the same place.

This would invalidate the hypothesis that the internet is written by insane people. It's just that any one site only includes 1% of the people, evenly distributed across all the sites.
