I want to point out two things about your video:

1. You should post these videos on Dtube as well and share that version on Steemit. That way you support both platforms. Of course, I'm not saying to abandon YouTube since that's the mainstream (for the moment! 😉). The only drawback is that you can't embed the video like you can do with YouTube, I think.
2. There IS an Instagram alternative in the making and it's actually based on the STEEM blockchain, using the Smart Media Tokens that were introduced recently. It's called Appics and I think it's got great potential. It's not yet in ICO phase but perhaps you could do a video about it.

Once again you've done an amazing video! I've taken your first course and I'm learning a lot! It's how I got engaged in crypto and basically the reason I'm here. Keep up the good work!
