Or maybe he’s right. But for the wrong reason.
“The problem of requiring HTTPs in less than 140 chars: 1.Few benefits for blog-like sites, and 2. The costs are prohibitive.
There’s actually a #3 (sorry) — 3. For sites where the owner is gone the costs are more than prohibitive. There’s no one to do the work.”
While this was more-or-less true-ish in times gone by, with the advent of truly-free SSL (and not merely the manual free edition you could get from StartSSL) from Let’s Encrypt (see my how-to), automated, hands-off maintenance of your SSL-iness is possible (and encouraged).
There are, potentially, good reasons for saying SSL won’t be required. But blaming costs, upkeep, and “few benefits” are not among them. If anything, SSL-ifying your blog will help with some (not all) attacks launched against self-hosted/-managed services where login data can be otherwise captured in plaintext.
Dave, I like you. But you’re wrong on this one.
