Maybe something like that could work. We could make a blog and post a riddle there. Then, in the comments on the page of the answer it would lead to, we could write the next riddle, and so on and so forth. If users go around the pages, trying to find the ones with the riddles in the comments, they might see the grammar and be tempted to correct it, thus editing pages and being active.
