Markdown is a terrible language

A critical deep-dive into Markdown's fundamental flaws, covering its ambiguous syntax (multiple ways to write bold/italic), inline HTML security vulnerabilities including ReDoS and XSS CVEs, context-sensitive grammar issues introduced by footnotes, and the feature creep that turned a simple transliterator into a full compiler. The author argues Markdown has been stretched far beyond its original purpose and advocates for a purpose-built markup language with a proper build system, unambiguous syntax, and well-defined shortcodes instead of continuing to bolt features onto a broken foundation.
