BlogPing is a small PHP web application similar to Ping-o-Matic. It allows people using services such as Blogger (which I’m using to manage this site) to notify weblog aggregators and services such as Weblogs.com, Technorati, Bloglines, and others that their weblogs have been updated.
I uploaded and released the first version of BlogPing earlier today. You can download BlogPing 1.1 and give it a whirl.
