How long is a piece of string?

Or a blog post? Should we be optimising not just our web applications, but our content, to be more digestible on the latest PDAs/iPhones/Feed readers? I’d like to post more images on this blog, but since it’s hard to find images relevant to the text, I prefer to leave them out rather than clog up my readers’ bandwidth with irrelevant content

How do you go about self-editing on your blog? Do you say what you want, or read it over and over until it’s as finely optimised as that Towers of Hanoi application you created at college?
