The great thing about hosting your own website is that you can decide for yourself what "standards" and "recommendations" actually make sense for you.

> By the way, andros.dev has an RSS feed.

You should add <link rel="alternate"> links to the RSS/Atom feed. The way people (or at least I) discover RSS feeds is to paste the blog/article URL into my feed reader - if that can't find the feed then I more than likely just give up and move on. All I can find on your site is a button in the side bar that doesn't even work.
