If you post your resume on the web, you are subject to huge spam. If you post your resume here, you can choose to receive or not receive emails. You can filter email job announcements based on whether you want to see jobs from employers or recruiters, full time or contract, and your geographical preferences. The manager's spam filter only allows people with the right citizenship to apply. To enable the spam filter post your email address in the application, but not on the resume, nor in the job description.
Google says they want to "organize the world's information", but they do not do such a good job organizing the world's resumes. A Google search for a resume does not tell you where the person is willing to live and work. Google search also does not tell you their years of experience with this technology, and what their citizenship or work visa status is.
