Ping blog directories for blog promotion

Once you have submitted your blog to the directories mentioned in this post( http://zerodollarchallenge.blogspot.com/2008/01/submit-your-blog-to-blog-directories.html ).You can think of pinging the blog directories. While the blog directories will index your blog periodically, sometimes you would want them to index your blog soon after you publish your new content and you stay ahead of competing blogs. By manually sending "pings" you will notify the blog directories of fresh content. You can use any one of the following "pinging services":
