Hi @gymnastly and welcome to Steemit,
Thank you for validating your YouTube channel and I'm impressed by your consistency through that medium.
There was a user here who used to write about gymnastics a lot - I can't find their profile at the moment but when I do, I'll ping you a link (and hopefully they'll still be active).
As you probably know, every social media has its own nuances and Steemit's no different. Although gymnastics isn't for me (you can try to convince me 😉), I think that your content could do well here and I'd be happy to help you get under the skin of the platform if you'd like?
To start off, a few key things to bear in mind:
Avoid plagiarism - if you use another site as a source (for images and text), then be sure to cite it. There's a team of people who'll pick you up on this if you don't.
AI generated content - As somebody who works in content marketing, you'll understand this better than anybody. Steemit rewards users on the concept of "Proof of Brain" so if the content you're sharing doesn't come from your brain and it's AI assisted, be sure to mention this.
Avoid Reposting - I've noticed that you've reposted the article that I commented on. This is a no-no as it could be considered "Reward farming". I prefer the layout of your more recent post and if you want to update the layout, you have the option to Edit something you've already submitted.
Cross-Reference - Like I asked you to validate your YouTube channel, I'd suggest continuing to cross reference Steemit with YouTube (and any other platform that you post on). This'll help with any accusations from point 1!
As a tip, I'd suggest keeping your content within The World of Sports community as you're more likely to attract a sport loving audience. Continue to keep the tags relevant but generally speaking, tags probably aren't the primary search method on the platform any more.
Anyway, a bit of a ramble from me. I'm curious about you... presumably you're American as you mention US Universities?
