One of the limitations of the Blogger platform is inability to send trackbacks when you make a post. A trackback is a simple acknowledgment, sent via a network signal (ping) from the originating site to the receiving site. Trackback requires both sites to be trackback enabled in order to establish this communication. A free service from Haloscan allows a blogger to send trackbacks to other blogs, and also display the trackbacks which have been sent to the blog. Haloscan also puts comments features on the higher level, allowing advanced comments management and enhanced performance. And, finally it offers blog visitors to rate blog entries, merchandise items, services, pictures, or any other objects on the site, based on a 5-star rating scheme.
