I've started using #share2steem which is the service that posts to Steem automatically from existing social platforms like Twitter and Instagram. I've also added YouTube and Medium, but I haven't got a Twitch (well not in terms of an account with the well-known game streaming platform anyway!)
You can see it and join up here - that's an referral link so if you use it, it will give me a little boost and you a little glow. Also subscribing to me on YouTube helps too.
As I say here in the video, it feels a little bit like gamification - there's a dashboard with oodles of stats and a leaderboard for the more competitive to watch obsessively, but it's not gamification for its own sake, you get Steem rewards and expose yourself to a potentially different community, not just a badge!
I've started a secondary Steem account at 
Happy to help if you try it and stumble!
