Anything more than 800 would not have fitted on the screen of this minibook that I am using to post this.

Extra columns could make the blog look more impressive & involve less scrolling up & down the page, if using a wide screen pc, but not everybody does.

At least now, if I am sat patiently waiting for a special train to appear, I can pass away the time typing away on this keyboard posting to the blog, or reading/writing e-mails.
