This question is in regard to the recommended use of the <-- more --> tag. It is not a support question, as I know how the tag works; it is merely a question for suggested use by more experienced useres.
I like to change the design of my blog fairly often. Previously I have displayed the full post of each blog entry on the blog home page. I find myself now wanting to show only a brief excerpt of each blog entry on the home page with a "Read More" link after each excerpt.
I wonder what the best way to do this would be, especially taking into account that I may wish to change it back to displaying full blog posts at a future time. Should the_excerpt be used, the <-- more --> tag, or perhaps some other method?
Also, I have not been using the <-- more --> tag in my posts. But I wonder if a person who might switch between showing full posts and excerpts on the home page might want to use the <-- more --> tag by default. If so, is there a way to have WP ignore the <-- more --> tag when you want to show the full post, and recognize the <-- more --> tag when you want WP to observe the content break?
