This introductory article discusses five essential elements of a weblog posting. Element one is use a catchy title, because as the author points out, some aggregators only display the title in the feed. The title should tease readers into wanting to read the article. The second element is to consider using an excerpt from a source such as another web page or news source. Commenting on the excerpt you quoted is the third essential element. The fourth element is be sure to link back to any excerpts you used from other sources, and finally use a photo if possible. This is certainly not a requirement as photos aren’t always possible or desirable.
