We often receive emails from our fans asking us to make changes to the site.  Over the past 6+ months, the most common complaint is from users who don't have Facebook accounts which preclude them from contributing to the conversations through the commenting system.  We love hearing from you and are open to suggestions.  Which commenting system would you like to use on PhoneDog?
