Just migrated my blog to Hugo. I host my blog on s3 directly, so the most time consuming step in the chain is uploading to S3. Stout and surge are nice pointers (thanks).

I'm currently using a simple script that pulls together fossil, s3cmd and gnu parallel to send the content over to s3. Fossil is used to track what changed, s3cmd is the work horse and parallel uploads multiple files at a time.

My vote for deploying static sites goes to https://surge.sh/. It's wicked simple and CDN backed!
