This is very ahistorical. There's long been consumer non-geek friendly online services. The typical AOL user in the 90s wasn't a geek by any means. They used chat rooms, instant messaging, and mailing lists via the user friendly AOL interface.

Facebook has long provided a user-friendly interface for non-geek users. It's filled with non-geeks generating content.

While the Internet has always had a geek contingent it hasn't been the exclusive domain of geeks for nearly thirty years.
