Hi, Baron, and Welcome to Steemit.
I trust you'll find this platform quite open to posts in many of your interests. As for your self-proclaimed "shitposts," it's probably a good idea to leave them on YouTube or other platforms. While there are a plethora of such shitposts on Steemit too, they are generally ignored, and earn only peanuts worth of Steem.
As for being introverted, that's hardly an issue here. I too am pretty much an introvert, such that I abandoned my F_c_Book account after being on it only a short time. Steemit is something quite different, offering a platform where you can upload your creative work and which is quite unlike the hyper-interactive networks of F___Book and the like.
Below are a few basic points of advice re posting on Steemit.
- Longer posts are more lucrative than short posts. If you make a post of 20–30 paragraphs, it's more likely to earn rewards.
- Include some photos, images or graphs, to complement the text.
- Make sure the text and photos are formatted properly, so that your post looks attractive and appealing.
Hope this helps for now. Good luck, and Full Steem Ahead!
