The Blogging Workflow
This is a very very nice summary of how blogs work by Roland Tanglao at Streamline, it complements my comments because it provides more details of some of the server side infrastructure:
1. Joe Blogger writes something and publishes it to his blog.
2. Joe’s Blog system updates his site’s HTML, updates his RSS file and sends a ‘ping’ message to the ‘Aggregation Ping Server’ indicating that his site has updated.
3. Search engines like Google and RSS specific services like Feedster, Technorati and PubSub periodically ask the Aggregation Ping Server, “Which sites have updated?”.
4. Since Joe’s site sends pings and has an RSS file and is easy to update frequently, Joe’s search engine rank is higher than a ‘normal site’.
5. Techie Teresa uses a program called an RSS reader to subscribe to Joe’s site. The RSS reader checks Joe’s RSS file for updates periodically (usually once/hour or once per day) and notifies her of Joe’s updates. Teresa no longer wastes time manually surfing Joe’s site. She just checks her RSS reader.
6. As a result, Teresa’s information flow is more efficient and she can monitor more sites in less time.
7. Joe Surfer (who is not related to Joe Blogger) still can access blogs the old fashioned, slow and less efficient way using his web browser and search engines.
