I do what they call "bible-dippin'" - where I open the bible to a random page and read. God has spoken to me several times when I did that, but I wouldn't really recommend it for beginner bible readers/newer Christians. It's not really a fruitful method, but that's what I do. I'm too disorganized at the moment to really stick to a bible reading schedule. *makes mental note to start doing that again*
For anyone who would like to browse through some reading plans, here's a good page to browse through: Zondervan Bible Reading Plans I like the way it goes by themes. I currently have the Heartlight bible plan - but haven't really committed to that. There are also plans in the back of some bibles =).
Just as side advice: If you have committed yourself to a bible reading plan, don't be discouraged if you get behind. What has happened to me is that I sometimes get behind and skim through some of the chapters just to catch up to the plan. And...that's not right. That's part of the reason why I discontinued. Whichever method you use to read the bible - make sure you read it properly in that it's read wholeheartedly (and not grudgingly - not because you have to, but because you want to) and it also should be read prayerfully...God speaks in those moments when you least expect Him to =).
