To generate this site, I’m using o-blog, written by Sébastien Gross. More precisely, I’m using the slightly polished set-up written by Sebastian Wiesner, at Lunaryorn.
Both developers themselves are already abandoning their own o-blog-based sites. Sébastien might still fix a few bugs, but Sebastian is already looking for alternatives.
It could mean that I’ll revamp the site again. But since all content is now managed in org-mode, I’m not worried much about the amount of time and effort that will require.
