I'm trying to decide regarding content of hover-cards. The conflict I'm trying to resolve is whether it's alright to direct to other pages on my site that can interest the viewer, or should I keep it more 'on-topic'.
Example: hover-card of a tag. Let's say a movie is tagged action. and when you hover it a card appears and offers you to also view action movies that were created in your location. And that he might want to check out top10 action movies. And that thrillers is a related tag, and maybe you'd like to see movies tagged thrillers.
Pros: I think this can help discover advanced site functionality. Cons: Not exactly 'expected' behavior.
What is your take?
