Thanks @siggy47 for putting this out there. I've participated in both and had been searching to see if these were still on. I like to see it continue so hope these suggestions can be of some help:

If we have writing contests in this territory the questions could be focused on a particular book/article that relates to Bitcoin and other relevant topics. You could also try them in other territories and have the contest prompt relate to one of the top posts to expand on others ideas.

Another idea is that you announce the book/article to read at the start of the month (or whatever timeframe), crowdsource the most interesting question/topic/idea related to it, then run a writing contest on it.
