The tag syntax here on this site seems to have no clear, specific purpose, and it's been used to refer to many different things on the 20 uses it has so far.
Most of its current uses are already well-covered by existing tags:
- Syntax highlighting: syntax-highlighting
- Markdown formatting syntax: markdown
- Search syntax: search
- Mathematics syntax: mathjax
I don't think this tag provides any meaningful categorization of questions.
Should we agree to remove it?
