" It's people using the WYSIWYG version of the text editor, and not really knowing what they're doing. It's unfortunately enabled by default. I turned it off for my account as I prefer to use the old (standard) method of typing posts.
You can disable it for your account by visiting the Look and Layout section of your profile, unchecking the bottom checkbox ("Show WYSIWYG editor on post page by default."), and clicking the "Change profile" button to save your changes."
