Late yesterday, this site underwent a minor, but significant, alteration. An account executive for my webhost sent email reminding about something already known: That today, Google would start aggressively designating sites secure or not secure, depending on whether they used https or http, respectively. The former is encrypted, and presumably safer to engage.
For many months, I had strongly considered moving to another host—not for dissatisfaction but to get more benefits while spending as much, or even a little less. But, as I have learned from painful past experience, migrating WordPress installations can go badly. Why take the risk, when everything works just fine? The account executive and I chatted about a pay-yearly discount (my preferred arrangement) to stay put and also purchase of a SSL certificate for encrypting the site. We reached an agreement.
