To be fair, static blog generators have been around for years, and their use is hardly a fad, considering the number of blogs that people host on github etc.

It hasn't caught on as much among non-tech types, but it's certainly not a fad, and the solutions are mature, usable and open source. I can understand wanting various features that only a dynamic blog offers (like commenting without Javascript), and I run such a blog myself.

There are tools for that as well. Staticman for example.
