"Alexa, ask subreddit heat what are the top posts on r movies"
"give me more details on that post"
"tell me the next post"
Subreddit Heat can tell you the hottest posts on a given subreddit. It will tell you titles of the top five posts on the subreddit at that time. If you want, the skill will also tell you details on a post, like the author, how much the karma the post has, or where the post was found.
