You could easily write some posts using this:

"Most common errors beginners make in Rust"

You're like the world expert on this.

"What people often get wrong about Rust"

Maybe there are common conceptual issues you spotted?

I'm not sure, but I would also imagine that you explained some things a few times in a more simple language, this could also be a great thing for a blog post. Instead of pointing them to a doc and explaining something about it, point them to your blog post then.
