Your website and blog are the equivalent of your locker at work
Don't be surprised when an employer asks you about the blog or website which you have helpfully listed on your resume.
Delete questionable or suggestive material. You may be applying to employers who routinely counsel their clients have their employees take down risque material from the locker room walls. Your blog or website are the equivalent of your locker room wall. You have invited scrutiny, and you will never know when it costs you an interview or an offer.
