Honestly? Don't.
Your goal for writing should be personal satisfaction, in my opinion. In the age of Twitter and microblogging, we've seen firsthand the effects of writing for other people, and it really gets on my nerves. When you bend over backwards to pander for others, it dilutes your personal message and encourages "novelty" visitors who are just there to gawk at your site or your writing style. It's no coincidence that some of the best blogs are just blank pages with normal text and fonts: the only way to build a decent following on a blog is offering a consistent, readable and interesting experience.
