You can add Yelp accounts into a Juicer feed. Simply add the final portion of the account's URL (the part after "biz/").
Please note that Juicer can obtain only the most recent three reviews from a Yelp page when you first add the source to Juicer, due to limitations of the Yelp API. New reviews should appear fine going forward.
