If I were the web master of any website, not just www.sanook.com, I’ll definitely use cookies. But, use it in the right way and do not make them doubt about their privacy (Making customers doubt about their privacy is bad for business.) I’ll use it so that they won’t have to do boring things more than once. (Like logging in to the website, answering security question) And I’ll use it to bring up contents that relate to their interest and think that it fit them most.
