A really big up for you, I launched my lib https://pithos.dev fews days ago, and I tried to coordinate posts on HN, Reddit, dev.to and Linkedin... but it was a failure because I didn't have accounts for HN and Reddit, so I was not able to post :) Now I understand I have to interact with people to win karma and it's a better way to share and communicate with a community ! Might be you could add this point to your guide ?
