I've been doing the Fractal Writing Contest for 6 weeks now. The first one had 3 entries; the 5th had 18! I am really happy to see the contest being popular and most of the entries are very good. What did I do? Nothing special, I try to vote and comment on each entry and I do not demand upvotes and/or resteems.

Participation is one thing, but profit is another. Most of the funding for each contest comes from myself with self-voting and upvote services paid by me. I'd like to have enough upvotes to better reward the participants, but I guess I have to wait. Good luck with yours!
