BLOGGER - Knowledge Base - How do I include multiple blogs in a single page?: "There are a number of reasons for including multiple blogs on a single page. Perhaps you'd like to have two or three users posting at once, but don't want the posts combined in a single blog column. Or maybe you'd like to post notes and comments in your sidebar that don't fit in with the rest of the content of your blog. It's even possible (depending on your server's capabilities) to grab blog content from another server and paste it seamlessly into your existing code. The possibilities are endless, really.

Including multiple blogs on a single page can be achieved through the use of includes. Includes are a feature on many different servers and platforms, including Server Side Includes, PHP, ASP, and Cold Fusion. The type of include method you need will depend on what kind of platform your server is running and whether or not your server has the functionality set up to do so. If you're not sure which of the following techniques are right for you, please ask your system administrator."
