My site is basically just a collection of articles so I would prefer a simple permalink structure, like: http://domain.com/%postname% That's how I did it before I switched to WP. However, I keep reading articles suggesting that you shouldn't begin your WP Permalink with %postname% due to slow access issues or something. Why does that matter? They say it's better to use %category% or a date first. Right now I have it set to domain.com/%year%/%month%/%postname%/ but that looks dumb and the date of publication is irrelevant to the article and it's extra crap for me to remember. Does it really matter? Were those just like old WP version 1.5 rules or something?
