bringing the users here but also on people who take the time to welcome and guide them

I read somewhere that the secret sauce to why TikTok is so addictive is that the algorithm gives one a higher chance to go viral when they're a new user. That initial dopamine hit keeps the creators coming back for more.

On the consumer side, having a good search and recommendation algorithm go a long way. I tried searching for posts / topics and it's quite hard to find relevant posts.
