That's the simply superb thing about blogging though. You write what you want for yourself with as many or as few words as you like. If bloggers got paid for blogging by the word or HAD to submit something every single day like journos or copywriters or other professional writers - blog world wouldn't be the fun place it is. As Muppetlord says, no one expects bloggers to turn out some insightful, witty, Pulitzer prize worthy stuff everyday - if they do fantastic and good for them - but I think it's the random every day stuff that makes it seem interesting and real and approachable.
