If you're new to blogging, you may still be fresh and innocent and think how wonderful it must be to have a venue for your random musings for all to read. If you've read any blogs other than those of yourself, your friends, and your neighbor's sweater-wearing chihuahua, you have likely found that approximately 70% of blogs maintained by actual people are self-described as 'random' or some essentially synonymous expression (see "stuff" in The Bitter Scroll's own subtitle). It's cute, in a wacky, slightly modern-rebellious kinda way. (Because, you know, not following the crowd is what everybody's doing these days.)
Unfortunately, what lacks in content will never be fully made up by form or medium of expression. The more readers who experience the wearing-off of the novelty of blogs, the more they will want some indication of content, some way to fit what you're likely to say into the vast hierarchy of knowledge and opinions. The more you leave it open, the more readers will fear pictures of pets or detailed descriptions of how you felt when you stubbed your toe yesterday.
The solution? Well, it depends if you think there's a problem, of course. If you really don't want to be heard--you just want to talk--blogging probably really is for you. (And easier on the rest of us. You can't click away from a RL conversation.) But if you want people to read your stuff, you need to give them a reason to read before they read. In the approximately 0.4 seconds in which they judge your blog worth it or not when they stumble across it, you need to convince people that your blog is worth reading. Then, of course, actually make worth reading.
I think we've got more than enough blue pills in the blogosphere. We could probably use a few more attempts to escape from the matrix of randomness and, ironically, uniformity.
