Told my friend that I was only on nostr. His response:

"Huh, I just read the webpage and none of it made any sense to me; sounds like cool decentralized stuff. Glad it's good."

I tried to mimic someone trying to learn about nostr by: searching "what is nostr" on Google, looking through the frontpage of nostr.com and watching the video. Video uses terms the average person knows / cares nothing about. I understand my friends response.
