Ahh thank you for that bit of insight, I was wondering if you had gone through the additional trouble of maybe pulling images from each respective topic via hashtag and applied some sort of ML to decide what picture is displayed with what category.

Definitely nothing wrong with the approach you've taken though (and if nothing else, consider the above an idea if you do decide to rewrite that functionality) if it helped ship the product more quickly, like I said-it doesn't break functionality, just a passive observation that may help the user experience later down the line.

Cheers :)
