True, I can also imagine different directions.

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.
