I tried manually typing a handful of common feed URLs relative and absolute, a firefox feed auto-finder extension, and a quick ctrl-f for feed in the source. But I guess if running an application is required for your webpages I'm better off not subscribing. That's not my kind of jam but it is understandable if your blog is for profit or it's purpose is to get you a job or something.
That's why I created a modal that explains the different RSS feeds for subscribing and their possibilities. My blog is over a decade old, and I've never used advertising, had sponsored articles, or tried to monetize it (except for asking for donations to maintain the server). I've written freely, sharing knowledge, creating tutorials, and developing courses. Your comment makes me lose the motivation to keep doing it.
