Getting a curie upvote back then 2017 was a huge deal breaker. I still remember the experience on getting one from the team and I felt that it already sealed the deal in the blockchain back then.
Your point is true especially the engagement since now I had been part of some communities, engagement and leaving meaningful comments is something that most people are lacking. I had been reminding people to expand their reach and get in touch with like-minded individuals for them to grow but I guess we really cannot force them to do so. People will still post and go.
Happy to hear it was helpful! Back then it all lacked organization so new users couldn't get the hang of it and so many left. But yes now with the communities and active users and curators it's easier to feel welcomed. Engagement is very important and a natural thing I would say.
