Not that I'm aware of. Google Flights has good data (such as price change data), but it feels like any other search app. Adioso felt more like Pinterest in some ways, where I could have a vague idea of how I wanted to travel, and then explore different trips based on that. Even just big photos (IIRC) of different cities gave some idea of vibes.
I've looked for other booking sites that helped me determine where I want to go, but haven't found anything else similar sadly.
