Well, you have a niche, which is running contests and games for your followers. There are people on here who are content creators of some sort (poets, photographers, essayists, etc.) and there are people who are community builders, and you’re very much in the second category, which is not a bad thing at all! Niches aren’t as important here as I would have thought but in your case you’re so firmly in the community building category that I think you should stick to it. If you want to get into writing content, it might get drowned out with all of the contests, so you could try making a second account just for your writing and resteem onto here. This is just a general comment but I’ve found that requiring resteems on contests really cuts down on the amount of people who enter because people don’t want to spam their own blogs if they’re trying to create their own niche, so it’s better to either ask people to resteem without requiring it or offer a slightly better chance if they do.
