Is there a benefit to leaving reviews on Expedia? On travel.stackexchange.com answering questions that are upvoted will get you privileges and potentially badges as well.
On ebay.com leaving feedback might make the other person you're doing a transaction with more likely to leave you feedback, which bolsters your own rating. I.e. an eBay seller may be disinclined to leave feedback if they see that you've never left feedback yourself.
But on expedia, is there any benefit, be directly or indirectly?
