I joined recently, and my first impressions was "wtf is this"?! By default I was following 100 bitcoin people, most of them looking like spammers. 
Luckily, one lady liked and zapped my post and it was a moment when I realized how powerful this protocol is. Especially for people like me who are normies as this community calls us, old school, not owning bitcoins...I embraced nostr and devoted a lot of time to unfollow many accounts I have nothing in common with. If nostr has a plan to make this mainstream, it needs to make onboarding more welcoming, but also find a way to render complex technical terms into simple and relatable language that avarege human being can understand. 

 yup, not the best onboarding experience
lots of unfollowing to do...
