Hello, just wanted to share my post on dev.to which is kind of an overview of ARC/ORC. I don't have experience writing posts like that, so please point out to errors if you find any :) I think that one of the ways to promote Nim is to write posts like that on different websites (habr, medium, dev.to, etc).
Post itself is <https://dev.to/yardanico/what-are-arc-and-orc-in-nim-3191>
