One minor note: jekyll definitely was not first to introduce front matter (though they may have introduced yaml front matter?). I am sure that at least pyblosxom had it earlier: https://pyblosxom.github.io/Documentation/1.5/writing_entries.html#metadata https://pyblosxom.github.io/Documentation/1.5/writing_entrie... Here's the earliest surviving commit showing blog entry front matter in 2002: https://github.com/pyblosxom/pyblosxom/blob/f80cdb42eb37ee0e7d4e7776f206e519b7452d99/libs/pyblosxom.py#L178 https://github.com/pyblosxom/pyblosxom/blob/f80cdb42eb37ee0e... My recollection is that blosxom (a perl blogging engine) had front matter as well, but I can't find any evidence of it.
