I was wondering if it'd be sensible for Danbooru to automatically add tags as a part of the commentary when uploading from Tumblr. Unlike, say, Pixiv or Twitter, where tags have a near-exclusively identifying purpose, on Tumblr it's customary to add little notes or "whispered text" not in the main post, but in its tags.
For example this Tumblr post, outside of tagging the characters, ship, fandom and a personal post tag, the author also placed a small note about the artwork itself ("why did i spend so much effort on a meme laced with a fuckton of irony for waving's 2nd anniversary.")
