That's reasonable :) I love Jekyll, so I have no objection to you switching. Just pointing out that there were probably much faster ways to get the same speedup.
Feel free to email me if you need any help getting the last bits figured out. I use jekyll for blog.danieljackoway.com and danieljackoway.com, and I've done some weird stuff with it (like pages that are generated purely through the layout + YAML frontmatter--no "content"). Plus I'd just like to see the redesign early :)
