A Practical Guide to RSS for Developers in 2026

RSS is not dead. It is the only feed format that has survived three format wars and the rise of centralized social timelines. For a technical blog, it is still the right default.

Why RSS for technical writing

• Plain text. Works in any reader, in any terminal, behind any firewall.
• Pushed to the client. The reader polls; you do not need a notification system.
• Stable URL per item. A permalink is the contract; everything else is decoration.

Fields we always set

• <title>
• <link> (absolute, canonical)
• <guid isPermaLink="true">
• <pubDate> in RFC-822 form
• <description> for the teaser

Fields we skip

Enclosures for podcasts (wrong use case), media:thumbnail (we do not host thumbnails), and the dozen author namespaces. Keep it boring.

Validation

The W3C feed validator is strict on dates and on the atom:link rel="self". YJTOON's RSS passes the validator on every build, and the build fails if it does not.
