Promoting on pinterest and tumblr

I know pinterest is popular and can be useful in promoting your art. But what about tumblr (in 2025)? I am over 30 and I remember tumblr the first time around (and yes, have some nostalgia towards it). But in 2025, are younger kids rediscovering that platform? I honestly am not social media saavy at all, but I remember tumblr was extremely visual and basically a predecessor to pinterest in a way. Anyone here use both to promote/share their art to try and grow your potential audience? (Most of my friends are 30+ so I really don't know any younger people to ask.) Thanks for reading x
