The code is all ready to roll in Github, but you probably knew that :)
IMO what makes dev.to work is the way the community formed and is carefully tended / moderated, which needs the right humans with enough time and excellent empathy.
Until recently I operated / helped moderate a family forum for many years, and that was a similar experience, starting small, existing for the users, not as a funding vehicle for the creators, having a niche topic (larger families).. technically we have now moved to a private Facebook channel 'cause the forum software was seriously old/dead, but the community remains.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
