Smart! The tag warrants some filling. I only saw 3 entries so far. It's a fun and dynamic genre.
In the future we could maybe look into some storygame categories. Looking into some older threads, I had heard that we don't have much family friendly content, so it might be handy to do a future event perhaps. (Furthermore, the historical section also maybe needs some filling)
I'm also bored, so I did some counting. Out of all tags, I spotted some kind of dumb ones, that aren't that descriptive and kind of vague. (Mainly the spiritual and psychological tag. Can someone tell me what "spiritual" means, it sounds to me like esoteric yoga class drabble.)
So I compiled all the tags that have 20 or less entries.
Western(13) - war(20) - villain protagonist (11) - thriller(9) - supernatural (9) - superhero (7) - sports (2) - grimdark (18) - foreign language (9) - edgelord (18) - family friendly (10) - cyberpunk (3) - anti-hero (18) - biblical (6) - LGBT (10)
Since the edgelord contest was pretty recent, I think that all the anti-hero and edgy tags can wait a little more. So my suggestion is to maybe look into the tags war, superhero, sports and western. The reason is mainly that I find them to be broad enough to allow people to play with these kind of concepts while also being a thing that is already well-defined in media and the general public. They have all room to grow and I myself would like to see more works with a western flavour.
I swear that my secret intention is not to flood the site with zombie cowboys in space though it would be pretty cool.
