@Ran Elkobi This thing is possible to show on blog view but in blog view user cannot rate thats why we have disabled it at blog view. if you required badly you can create ticket and we will take a look at that . Module support is not possible in current architecture.
Item rating is cool but i really need a solution to see the overall rating of each article on the blog with a rate order (ex :best rate content to worst rate content like in Tripadvisor). Are U working on it for next versions ?
