I moved my own site to Jekyll recently. With modern javascript techniques a "static" site can still be pretty interactive without any dependencies on fragile software plumbing. It's also really fast.
I've been using NestaCMS for a year or two now, kinda feel it's the best of both worlds. Low-tech enough that I can just write a markdown file in vim if need be, but the flexibility to do something dynamic if the need arises.
