I often remark that IT in general is a history-less space. I wonder if Tom would have developed Jekyll if he knew about Blosxom? Blosxom had its last release in the same month when Jekyll had its first.

The blog post seems to imply that he came up with the idea and code for Jekyll all by himself. But also as he's a Ruby guy, it's likely he would have ported over the code and concepts to his own project.
