Eddie ditched SquareSpace¹ and moved to Jekyll:

Jekyll is not the first static platform I’ve attempted to move to, and I’m grateful my previous attempts to move to other static frameworks failed because I can’t think of a better place to be than Jekyll now—although many, many good static site options now exist.

It's no secret that I prefer static to dynamic sites. A lot. I chose Pelican, but Jekyll was a close second choice.
