Do you use them? If so, what's your take on them?
Personally, I love them. I think they're super-handy for cranking out batches of images (say, for stock image collections) where you need that style consistency. I also love to use them for exploring new styles by using them in various combinations with srefs and render styles in the prompt.
I spent a lot of time creating moodboards when the feature was in beta. Here are some of my favorites:
Moodboard: Moodboard #1 - Scifi & Fantasy Characters - I built this one 100% from Leonardo AI images (I wish I could trace the fabric references for those back to the source - those in turn were created using Leonardo's Style Reference feature in the AlbedoBase XL model.) Moodboard: Moodboard #17 - Liminal Spaces - not a lot of images, but I quite like how this one adds to environments. If you don't know what "Liminal Spaces" are, look up the Backrooms or Pool Rooms "found footage" on YouTube - fun stuff, and I'm obsessed. Try these out in your next project and see what kind of fun results you can get. And if you're a Moodboard creator, feel free to share yours here!
