If you participate do you have to start from scratch?
To be eligible in voting and for the prize money, yes. But if you are already working on something we still encourage you to join and use the challenge to launch and/or get things shipped! It's a fun, positive community that has been motivating lots of ppl :)
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.
