Ever since I gave Eleventy a go when I was building the LeedsJS website, I've been a huge fan and advocate, even convincing some people to give it a try out of my sheer enthusiasm for it. I absolutely love the simplicity and flexibility of it, as well as things like data files. I have a whole post talking about this stuff from when I was building the new LeedsJS website.
I've been meaning to convert my own site over for a while, and recently took the plunge and decided to do it. As well as giving me the opportunity to dig into Eleventy without a deadline pressing me, it also gave me the chance to make some stylistic changes.
