I think it could be useful to have several categories of tag
- topics: science, art, politics, etc.
- purpose: news, opinion, explanation, introduction, humor, etc. (for example, anything from producthunt.com is introduction)
- format: text, audio, video
I think it's good to have wide coverage, because it means much better filtering/sorting, both for manual and automatic.
