I've been wondering, should stuff like
- Year of Creation (2020, 2021, 2022) be included
- Commission (If the piece was a commission for someone)
- Western/Eastern (To separate Comic/Cartoon and Manga/Anime)
- Program Used (Photoshop/SFM/Blender etc.)
- Digital/Traditional/3D
- Color/Greyscale/Lineart
- Lowres/Highres/Absurdres

I believe these are important as someone who regularly use R34 but what do you think?

Some of those are indeed already tags that are used here, like absurdres, greyscale, lineart, traditional, 3d, blender, and western. To me, lowres and eastern/manga/anime would be the most useful of the ones we don't use.

Also, for future reference, there's a forum for tag questions.
It got a bit buried, so here's the link: hypnohub.net/index.php?page=forum&s=view&id=51288

Man, I've missed a "manga" or "Eastern" tag of some sort on this website so damn much, since there's a lot of good manga MC scenes and sometimes I'm just in that mood. It does sound like a lot of work to add, though.
