I'm now trying out ox-hugo. I still like o-blog, but i felt like trying something new!
During the conversion I had great support from Kashual Modi, the author of ox-hugo. It is an interface between org-mode and hugo, the static web site generator. I also had support from the author of hugo-bootstrap-premium mode, and Artem Sidorenko, who implemented the nice logarithmic tag-cloud in the sidebar of this site.
