Hans… thanks for the mention… I’d like to clarify that if a site is a simple personal blog or some other kind of site where there is no sensitive data — and I would define sensitive as personally identifiable info, proprietary info, or competitive business information — stuff a competitor in your market would benefit from obtaining — then there may be little reason to worry about a loss of confidentiality, integrity, or availability. Those three things are the foundation of cyber security.

In that case, Let’s Encrypt might be a perfectly suitable solution if the only purpose is to pass muster with Google’s ranking algorithms.
