Limit Access to your blog
Just a helpful suggestion, if you're going to blog about your job/personal details, you probably want to go ahead and block access from your employer/stalker ex-boyfriend.
You don't have to have a "private" or password protected site, in many instances a simple addition (or creation) of an .htaccess file will suffice. For the less technically inclined, HTML Basicx has an online .htaccess block access generator. This is not a fail-safe plan, but it certainly beats no plan at all.
