I think the usefulness of a SSG really depends on your goals. If your goal is simply to publish a blog, perhaps a SSG is not the right solution for you. SSGs are interesting because they have zero external dependences. I can just deploy my blog to Amazon S3, use CloudFront if I so choose, and never have to worry about scalability or how much traffic my blog can handle. To me, that is more important than the perceived friction that it takes to get a post online.
