There are a number of blogging services designed specifically for tracking and connecting blogs. Why Ping? Pinging lets dozens of blogging services know you’ve updated your site and increases traffic to your blog.
Most modern blogging software packages ping at least one update service, and there are likely plugins or extensions to ping more, but often this requires more work on your part and can slow posting down to a crawl if the service is slow to respond.
