Problem: we need a way to identify questions about specific topics. As a visitor, I want to refine my search using well-identified categories (for example: programming language, geographical location, plant, tractate, …). As a potential answerer, I want to browse (or receive notifications about, etc.) questions about the topics that I’m an expert on.
Solution sketch: tags work well on Stack Exchange.
- Each question has 1–5 tags.
- Tag names are ASCII letters and a few punctuation signs.
- Anybody with a certain privilege can create a tag.
Justification for MVP: a dozen posts in, we already find the categories on this forum too restrictive, and aren’t happy that only admins can create categories. The early days of a site are when a lot of tags get created, so we need a low-friction way to do that.
We may want to refine how they work, to have fancy displays, to allow non-ASCII characters, to add tag wikis, to add tag-specific guidance, to have renaming and mass-retagging tools, to define synonyms, maybe <gasp> have some form of tag hierarchy. But none of that is MVP.
